Franklin Electric Water Truck Pump Models: XS439 and XS869

The XS439 is a 3-inch discharge × 4-inch suction pump with a nominal 9-inch impeller. The larger XS869 uses 6-inch discharge × 8-inch suction connections and is listed with a flanged volute. Both belong to Franklin Electric’s 9-inch water-truck pump family, but their operating curves and connection dimensions differ. Select by your truck’s required flow at discharge head and pump speed, not by the family’s maximum capacity alone.

Franklin’s published catalog gives up to 2,000 GPM, up to 260 feet of head, 250 PSI maximum working pressure and 212°F maximum liquid temperature as family-level limits. These do not describe one simultaneous operating point or establish that every XS439 configuration delivers 2,000 GPM. Verify the separate 3 × 4–9 and 6 × 8–9 performance curves before sizing a system.

Water Truck Pump Technical Specifications

Connection Sizes and Volute Options

How to Choose a Water Truck Pump

• Drive type: Match the pump to your truck’s belt/PTO arrangement or to its hydraulic motor. Hydraulic models require correct SAE B-fit or C-fit coupling and mounting.
• Rotation: Select clockwise (CW) or counter-clockwise (CCW) facing the pump shaft. Both appear in XS439 ordering configurations; the supplied XS869 entries show CW.
• Connections: Select NPT-threaded or grooved (Victaulic-style) XS439 ports, or the XS869 flanged option, to suit existing plumbing.
• Shaft seal: Choose the packed-box configuration if field packing service is preferred, or the mechanical-seal version if specified for the installation. Seal materials and options must match the pumped liquid.
• Operating point: Match pump speed, flow, head, driver power and suction conditions using the size-specific performance curve. Confirm model availability and any nonstandard impeller trim before ordering.

XS439 Model Number Guide

Additional seal and connection suffixes: NP denotes an NPT connection with packing, NM denotes NPT with a mechanical seal, VP denotes grooved connections with packing, and VM denotes grooved connections with a mechanical seal. Always check the complete SKU; the seal and volute choice are not interchangeable by name alone.

Belt Frame vs. Hydraulic Drive

Franklin’s documentation describes SAE B-fit as a 13-tooth involute spline with 16/32-inch pitch and SAE C-fit as a 14-tooth involute spline with 12/24-inch pitch (both 30° pressure angle). Confirm shaft dimensions, hydraulic motor mount and direction of rotation against the actual equipment before ordering. The hydraulic motor and power source are separate integration considerations.

Complete XS439 and XS869 Ordering Information

The table below combines all 30 supplied configurations, including the original 24 linked XS439 item numbers and the six XS869 items from the older technical page. Select the exact combination of model, connection, rotation, shaft seal and drive fit. Listed weights and configuration details are from the supplied source documentation and should be confirmed for a replacement unit.

Ordering notes: BF = bearing frame; HB/HC = hydraulic with B-fit/C-fit respectively. The listed pumps use cast iron impellers. Franklin’s catalog notes that a nonstandard impeller trim may carry an additional charge. Contact Ken’s Distributing for current ordering and availability details.

Construction and Service Features

Heavy Cast Iron Volute

The cast-iron volute uses a back-pullout arrangement that provides access to the rotating assembly for service. The volute can be oriented to suit the installation, subject to the manufacturer’s mounting and piping instructions.

Enclosed, Double-Keyed Impeller

The supplied XS439 and XS869 pump configurations use an enclosed cast-iron impeller with a double-keyed shaft connection. Select the correct clockwise or counter-clockwise impeller and volute for the exact pump model; these are not interchangeable without manufacturer confirmation.

Packing or Mechanical Shaft Seals

Packed-box versions use a serviceable packing ring and gland. Mechanical-seal versions use carbon/ceramic faces with nitrile (Buna) elastomers and stainless components, according to the series catalog. Follow the applicable seal instructions for adjustment, lubrication and water compatibility; do not run the pump dry.

Bearing Frame and Replaceable Shaft Sleeve

Heavy-duty bearing-frame construction, an oversized shaft, externally accessible grease fittings and a replaceable shaft sleeve support long-term maintenance. Use the specified lubricant and service interval for your exact frame and duty conditions.

Common Water Truck Pump Applications

• Dust control on construction sites, mining haul roads and unpaved roads
• Road-building and grading water distribution systems
• Water tanker filling and discharge operations
• Agricultural irrigation and field water delivery
• Municipal street washing and construction water support
• Industrial water transfer using truck-mounted or skid-mounted equipment

Applications involving potable water, firefighting certification or chemical transfer require separate verification of approvals, pump materials, flow requirements and operating procedures.

XS439 and XS869 Replacement Parts: Bearing Frame

The following manufacturer-referenced engineering table retains the original figure numbers, parts for both pump sizes, construction materials and shaft-kit references. Several part entries depend on whether the pump uses a packed box or mechanical seal.

Bearing-frame historical compatibility: The supplied technical references identify drive-side thrust ring 305462027 (figure 42) and retainer 305462026 (figure 43) on configurations manufactured before June 2013. Later assemblies use bearing nut 305463039 (figure 38), lock washer 305463042 (figure 39) and lip seal 305463148 (figure 26B). The supplied shaft replacement kits are 305731901 (XS3x4-9) and 305731903 (XS6x8-9). Confirm pump serial number and production details before substituting any historical part. Original source entries are retained in the tables below and may need manufacturer verification for supersession.

XS439 and XS869 Replacement Parts: Hydraulic Drive

For hydraulic-drive pumps, use the following model-specific repair matrix including SAE B-fit/C-fit motor mounts, hydraulic shaft couplings, shaft components, seal options, bearings, gaskets and hardware. Match the pump size and hydraulic drive fit before selecting replacement parts.

XS439 and XS869 Dimensional Information

Use the diagram and full source measurements below to plan mounting and shaft alignment. Dimensions are in inches and are supplied for estimating purposes. Refer to the exact model drawing before fabricating permanent mounts or modifying truck plumbing.

Drive spline sizes and dimensional columns depend on the mounting type, so do not apply dimensions for one hydraulic fit to a different drive configuration.

XS439 and XS869 Performance Curves

The 3 × 4–9 XS439 and 6 × 8–9 XS869 have different performance curves. Flow changes with impeller trim, speed and total dynamic head. Use the curves to size a model at your required duty point rather than treating family maximum capacity or pressure as the pump’s operating output.

View the existing Kendisco XS439 / XS869 performance curve PDF or consult Franklin Electric’s water truck pump technical catalog (PDF).

Installation, Pump Sizing and Maintenance Considerations

• Mounting: Follow the correct vertical or horizontal mounting arrangement and secure the unit to a suitable truck or skid structure.
• Suction and discharge: Select hoses, grooved couplings, threads or flanges suited to the exact order number. Reduce avoidable friction losses and ensure suction-side connections are airtight.
• Rotation: Verify CW/CCW from the manufacturer-defined shaft viewing position before coupling the driver. Do not run a pump against its specified rotation.
• Hydraulic drive: Match the motor mounting, B-fit/C-fit spline, required RPM and torque to the truck’s hydraulic system.
• Priming: These end-suction centrifugal pumps are not described as self-priming. Follow the pump installation manual for flooded-suction or foot-valve/priming provisions where applicable; never run the pump dry.
• Seals and bearings: Inspect packing or the mechanical seal, monitor bearing condition and lubricate per the manufacturer’s maintenance instructions. Packed glands require the correct controlled leakage per manufacturer guidance, not an assumed universal drip rate.
• Service history: Confirm manufacture date, serial number and shaft-kit revision when replacing older bearing-frame or hydraulic-drive parts.

Frequently Asked Questions About Franklin Electric Water Truck Pumps

What is the difference between the XS439 and XS869?

Both are part of the Franklin Electric 9-inch water-truck pump family. XS439 is the 3 × 4–9 size with 3-inch discharge and 4-inch suction; XS869 is the 6 × 8–9 size with 6-inch discharge and 8-inch suction. They use different hydraulic curves and have different available volute configurations.

Can an XS439 deliver 2,000 GPM?

The published 2,000 GPM capacity is a maximum for the larger 9-inch water-truck family, not a verified XS439 duty point. Use the manufacturer’s XS439-specific 3 × 4–9 performance curve to determine flow at your pump speed and required head.

Which rotation should I order?

Choose clockwise (CW) or counter-clockwise (CCW) to match the pump-side rotation when facing the shaft. XS439 model numbers are available with both rotations. The XS869 models in the supplied ordering table are clockwise. Confirm with your truck’s drive documentation.

What is the difference between SAE B-fit and C-fit?

These are different hydraulic-drive interface specifications. The manufacturer lists B-fit 13-tooth, 16/32-inch-pitch and C-fit 14-tooth, 12/24-inch-pitch splines. Match both the mounting and coupling to your hydraulic motor before ordering.

Do XS439 pumps come with NPT or Victaulic connections?

Both are represented in the XS439 ordering table. NP/NM configurations have NPT connections, while VP/VM versions have grooved (Victaulic-style) connections. The XS869 configurations listed here are flanged.

Should I choose a packed-box seal or mechanical seal?

Both are available. Selection depends on your maintenance approach, duty conditions and pumped liquid. Use the suffix and exact order number to choose the specified configuration, and check material compatibility before ordering.

Can I order replacement parts for a pre-2013 water truck pump?

The historical parts notes and replacement shaft kits are retained above. Provide Ken’s Distributing with your model, serial number and original part number so the proper supersession can be checked before an order is placed.

Does an XS water truck pump need priming?

XS439 and XS869 are end-suction centrifugal pumps. They should not be assumed self-priming; follow the manufacturer’s installation instructions for suction arrangement, priming and dry-run protection.
