Franklin Electric XS Series Frame Mount Centrifugal Pump

The XS Series Frame Mount Centrifugal water Pump is a heavy-duty, industrial-grade water pump built for applications where reliability, high flow volume, and flexible installation matter most. Available in 9-inch and 13-inch configurations, the XS Series handles everything from agricultural irrigation and water truck service to construction dewatering, municipal systems, and mining operations. At Ken’s Distributing Company, we stock the XS Series and can help you select the right model, seal type, and rotation configuration for your specific setup.

What Is the Franklin Electric XS Series Frame Mount Pump?

The XS Series is a frame mount centrifugal pump, which means the pump and motor are separate units mounted on a common base frame. This is different from a close-coupled pump where the motor and pump share a direct connection. The frame mount design allows the XS Series to be driven by a belt drive, engine drive, PTO shaft, or direct-coupled electric motor, giving you the flexibility to power the pump with whatever drive source is available at your job site or installation location.

The frame mount configuration also makes the XS Series easier to service. The pump end can be removed and rebuilt without disturbing the motor or the drive setup, which reduces downtime and keeps maintenance costs in check on a working pump that runs hard every day.

Kendisco is an authorized Franklin Electric distributor. Every XS Series pump ordered through Ken’s Distributing Company is a genuine Franklin Electric product with full manufacturer backing and access to real replacement parts.

9-Inch XS Series Construction Details

The 9-inch XS Series is the workhorse configuration used most commonly on water trucks, irrigation systems, and construction sites where you need a compact frame mount pump that can take daily abuse and keep running.

• Volute: Heavy cast iron construction with a back pullout design. The volute can be rotated to different positions during installation, which makes it much easier to line up suction and discharge connections in tight or awkward mounting situations.
• Impeller: Cast iron enclosed impeller for high hydraulic efficiency. Double keyed to the shaft for improved reliability under the torque loads common in belt drive and engine drive configurations.
• Seal: Available as a packed box seal or a mechanical seal with carbon and ceramic faces, BUNA elastomers, and 300 Series stainless steel hardware. The packed box option is often preferred on water truck installations where regular adjustment is part of normal maintenance. The mechanical seal is better suited for unattended operation.
• Bearing Frame: Heavy duty iron bearing frame with an oversized shaft and max-life bearings. External grease lubrication fittings allow bearing service without disassembly. This is a detail that matters a lot on pumps running in dusty or abrasive environments.
• Mounting: Can be installed in vertical or horizontal orientation to fit the mounting constraints of your truck bed, skid, or pad.

13-Inch XS Series Construction Details

The 13-inch XS Series steps up to higher flow capacity for large-scale agricultural irrigation, municipal systems, and heavy industrial applications where the 9-inch model does not have enough volume.

• Volute: Cast iron for heavy duty service with a back pullout design and rotatable installation. The 6×8-13 model features split volutes that reduce radial bearing load, extending bearing life on high-flow installations where radial forces are significant.
• Impeller: Stainless steel enclosed impeller configured for superior NPSH (Net Positive Suction Head) characteristics. Internally hydraulically balanced to reduce bearing load and extend the service life of bearings and seals under continuous operation.
• Seal: Available as a packed box with lantern ring for flushed packing installations, or as a mechanical seal with carbon and ceramic faces, Nitrile elastomers, and 300 Series stainless steel hardware.
• Motor: Standard 1800 RPM JP frame motor. Both ODP and TEFC enclosures are available depending on your installation environment. TEFC is the right choice for outdoor and exposed installations. ODP suits sheltered indoor installations.
• Mounting: Vertical or horizontal mounting options accommodate different installation configurations on skids, pump houses, and irrigation stations.

Applications and Industries

The XS Series frame mount pump serves a wide range of demanding applications across multiple industries. Here is where it performs best:

• Water Trucks: The 9-inch XS Series is one of the most common pumps used on water trucks for dust control, road building, and construction site watering. The grooved connection models fit directly into standard water truck plumbing configurations. Clockwise and counter-clockwise rotation options accommodate different truck-mounted drive setups.
• Agricultural Irrigation: Large-scale field irrigation uses the XS Series for high-volume water delivery from ponds, rivers, and storage tanks. The frame mount design allows PTO or engine drive where electrical power is not available in the field.
• Construction: Dewatering excavations, supplying water for dust control, and filling storage tanks on construction sites are all within the operating range of the XS Series.
• Municipal Systems: Municipalities use the XS Series in water distribution support, park irrigation, and utility pumping where long service life and easy maintenance are priorities.
• Mining: The heavy cast iron construction and oversized shaft on the 9-inch models handle the rough service conditions common in mining operations.
• Commercial and Light Industrial: Commercial facilities use the XS Series for water transfer, cooling water supply, and process water systems where a reliable, serviceable frame mount pump is needed.

Features and Benefits

• Back Pullout Design: The pump end pulls straight out from the back of the volute without disturbing the suction or discharge piping. This is a major time saver on service calls, especially on water truck installations where getting the truck back in service quickly matters.
• Rotatable Volute: The volute can be repositioned during installation to orient the suction and discharge ports in the most convenient direction for your piping layout. This flexibility reduces the number of elbows needed and simplifies installation significantly.
• Vertical or Horizontal Mounting: Installs in either orientation to fit your space and equipment constraints without needing different pump models for different mounting configurations.
• Clockwise and Counter-Clockwise Rotation Options: Available in both rotation directions to match the drive source rotation without adding a gearbox or additional drive components.
• Grooved and Threaded Connection Options: Choose grooved connections for quick-coupling plumbing systems or threaded FNPT connections for standard pipe fittings, depending on your installation requirements.
• Heavy Duty Bearing Frame with External Grease Fittings: The oversized shaft and max-life bearings handle the side loads common in belt drive applications. External grease fittings let you service bearings in place without pump disassembly.
• Packed Box or Mechanical Seal Options: Choose the seal type that fits your maintenance practice. Packed box seals are simple to adjust in the field. Mechanical seals are better for unattended or remote installations.
• Stainless Steel Impeller on 13-Inch Models: The hydraulically balanced stainless steel impeller on the 13-inch series delivers better corrosion resistance and longer service life in higher-demand applications.

XS Series Frame Mount vs. XS Series Close-Coupled: Understanding the Difference

Franklin Electric also offers the XS Series in a close-coupled configuration. Here is how to tell which one you need:

Feature	XS Series Frame Mount	XS Series Close-Coupled
Drive Type	Belt drive, PTO, engine drive, or motor	Direct electric motor only
Motor Connection	Separate, mounted on common base	Directly coupled to pump shaft
Footprint	Larger, requires base frame	Compact, no base frame needed
Best For	Mobile, remote, PTO applications	Fixed electric installations
Serviceability	Motor and pump serviced independently	Simple single-unit service

If you need to run the pump from a tractor PTO, a gas engine, or a belt drive system on a water truck, the frame mount is the right choice. If you have a fixed electric motor installation and want the simplest possible setup, look at the XS Series close-coupled pump instead. Call Ken’s Distributing at 303.699.7845 and we will help you decide.

Installation and Compatibility

• Rotation Direction: Order the correct rotation direction for your drive setup before installation. Clockwise and counter-clockwise models are not interchangeable after manufacturing. Confirm your drive source rotation before placing your order.
• Connection Type: Choose grooved connections for Victaulic-style couplings on water truck and industrial plumbing. Choose threaded FNPT for standard pipe fitting installations.
• Mounting Orientation: Both vertical and horizontal mounting are supported. Use appropriate isolation pads to reduce vibration transmission to the mounting surface.
• Bearing Lubrication: Use the external grease fittings on the 9-inch bearing frame at regular service intervals. Do not over-grease. Refer to the Franklin Electric service manual for grease type and interval recommendations.
• Seal Selection: If the pump will run unattended for long periods, the mechanical seal is the better choice. If you have regular maintenance personnel on site who can adjust packing, the packed box seal is cost-effective and easy to service in the field.
• Drive Alignment: On belt drive installations, ensure proper belt tension and pulley alignment before startup. Misalignment is the most common cause of premature bearing failure on frame mount pumps.
• Motor Enclosure: On 13-inch models, select TEFC for outdoor and exposed installations. ODP is appropriate for sheltered indoor pump rooms with good ventilation.

Replacement Parts and Service

The back pullout design of the XS Series makes service practical in the field. On water truck applications especially, the ability to pull the pump end and replace the seal or impeller without removing the volute from the truck saves hours of labor.

Frequently Asked Questions

What does frame mount mean on the XS Series pump?

Frame mount means the pump and motor are separate units mounted on a common base frame rather than directly coupled together. This allows the XS Series to be driven by belt drive, PTO shaft, gas engine, or electric motor depending on what power source is available at your installation site.

What is the difference between the 9-inch and 13-inch XS Series models?

The 9-inch XS Series uses a cast iron impeller and is most commonly used for water truck, construction, and moderate-volume irrigation applications. The 13-inch XS Series uses a stainless steel hydraulically balanced impeller and is designed for higher-volume agricultural, municipal, and industrial applications. The 13-inch models also offer split volute options to reduce radial bearing load at higher flow rates.

Can the XS Series frame mount pump be installed vertically?

Yes. Both the 9-inch and 13-inch XS Series models support vertical or horizontal mounting. The rotatable volute also allows you to orient suction and discharge ports in the most convenient direction for your installation.

What rotation direction do I need for my water truck?

The correct rotation direction depends on your drive source. The XS Series is available in clockwise and counter-clockwise rotation when facing the drive shaft. Confirm your drive rotation before ordering because the rotation direction is set at manufacturing and cannot be changed after the fact.

What is the difference between the packed box seal and the mechanical seal on the XS Series?

The packed box seal uses compressed packing material around the shaft that can be adjusted in the field by tightening the packing gland. It requires periodic adjustment but is simple to service. The mechanical seal uses carbon and ceramic faces to create a positive seal without adjustment, making it better for unattended and remote installations. The 13-inch packed box option also includes a lantern ring for injecting flush water into the packing.

Is the XS Series frame mount pump the same as the XS Series close-coupled pump?

No. The frame mount version is a separate unit from the close-coupled XS Series. The frame mount is designed for belt drive, PTO, and engine drive applications. The close-coupled version mounts directly to an electric motor for fixed installations. They share the XS Series name but are different products serving different installation requirements.

Can I order replacement parts for the XS Series from Kendisco?

Yes. Ken’s Distributing Company stocks genuine Franklin Electric XS Series replacement parts including seals, packing sets, impellers, and bearing kits. Call 303.699.7845 for parts availability and fast shipping.
