Selection note: The hydraulic motor is not identified as included with these pump item numbers. Confirm the motor supplied or retained, hydraulic system flow/pressure, shaft speed, and required pump GPM and total dynamic head against the applicable performance curve before ordering.
Choose SAE B or SAE C Hydraulic Motor Fit
| Hydraulic fit | Spline details | Model identifier | Compatible drive requirement |
|---|---|---|---|
| SAE B | 13 tooth, 16/32-inch spline pitch, 30° pressure angle | XS439-HB… | Match an SAE B hydraulic motor shaft and mounting interface |
| SAE C | 14 tooth, 12/24-inch spline pitch, 30° pressure angle | XS439-HC… | Match an SAE C hydraulic motor shaft and mounting interface |
The model designation identifies the requested hydraulic interface, but motor fit alone does not establish available speed or pumping capacity. Confirm the hydraulic motor displacement, allowable RPM, available oil flow and hydraulic operating pressure with your equipment specifications. Do not select B or C fit solely from tractor size.

Replacement Parts for XS439 Hydraulic Driven Pumps
Many XS439 service components are replaceable individually, so a worn seal, impeller, shaft sleeve or hydraulic coupling does not automatically require replacement of the complete pump. The manufacturer numbers below come from Franklin Electric’s 9-inch water truck pump hydraulic parts catalog for the XS3x4-9 family. For an accurate quote, provide your complete pump model, item number, rotation, seal style and hydraulic fit.

When to Repair an XS439 Pump vs. Request a Replacement
- Leaking at the shaft: Identify packing or mechanical-seal construction first. Request the matching packing set or mechanical seal, then inspect the shaft sleeve.
- Reduced flow: Check inlet restrictions, pump speed, air leaks, impeller wear and operating head before ordering a replacement impeller.
- Damaged volute: Specify CW or CCW rotation and FNPT or grooved ports. The volute case differs by these options.
- Hydraulic drive mismatch: Confirm whether the installed SAE B/C motor mount or shaft coupling is worn or simply incompatible with the motor you have.
- Major frame or multiple-component wear: Ask Ken’s Distributing to compare the cost of repairs with a complete replacement pump.
How to Select a Hydraulic-Driven Water Truck Pump
- Verify the power source: Identify the hydraulic motor make/model, available hydraulic flow and pressure, and expected shaft RPM. Do not assume the pump includes a hydraulic motor.
- Confirm rotation: Choose CW or CCW as viewed from the pump shaft end. Correct rotation is important for performance.
- Match plumbing: The XS439 has a 4-inch suction and 3-inch discharge, with either grooved or threaded FNPT connections by item number.
- Choose the seal: Select graphite/cotton packing for adjustable packed-box service or the mechanical-seal configuration where appropriate.
- Size the hydraulic end: Use the correct manufacturer pump performance curve for the required water flow and total dynamic head. The pump is not self-priming.
- Confirm working conditions: Check water characteristics, suction setup, mounting clearances, shaft speed and manufacturer operating limits.
Typical Uses for XS439 Hydraulic Centrifugal Pumps
- Water truck pumping: Hydraulic-powered tank discharge and dust-control systems when a compatible hydraulic motor and drive are available.
- Agricultural irrigation: Mobile field systems where auxiliary hydraulic power is used to drive the centrifugal pump.
- Construction water transfer: Portable water handling and site support with appropriate priming and inlet conditions.
- Municipal and industrial service: Mobile clean-water transfer where a 3 x 4-inch centrifugal pump meets the required duty point.
XS Hydraulic Drive vs. Frame-Mount Centrifugal Pump
| Selection | XS439 hydraulic drive | XS frame-mount / belt or coupled drive |
|---|---|---|
| Power and connection | SAE B or C hydraulic motor interface; requires suitable hydraulic power | Mechanical drive arrangement selected around an appropriate motor or engine |
| Available configurations on this page | 16 hydraulic XS439 combinations | Separate frame-mount models and configurations |
| Pump rotation | CW or CCW, as specified by item | Depends on selected frame-mount product |
| Wet-end style | Cast iron enclosed impeller and back-pullout volute | Depends on frame-mount family and hydraulic size |
| Buyer selection priority | Fit, rotation, seal, pipe connection and required pump performance | Pump size, speed, driver, seals and mounting arrangement |
If the application uses a separate belt, motor or coupling arrangement, compare the Franklin Electric XS Series frame-mount centrifugal pump. For pump or truck applications requiring self-priming operation, review the Franklin Electric FMIH hydraulic driven self-priming pump as a different pump family.
Frequently Asked Questions About XS439 Hydraulic Driven Pumps
Does an XS439 hydraulic pump include a hydraulic motor?
The listed XS439 items specify the hydraulic motor fit but do not identify a hydraulic motor as included. Provide your motor and equipment details so Ken’s Distributing can confirm the pump configuration and quote scope.
What is the difference between an SAE B and SAE C fit?
The SAE B interface has 13 teeth and 16/32-inch spline pitch. SAE C has 14 teeth and 12/24-inch spline pitch. Match the actual motor shaft and mounting interface rather than assuming the fittings interchange.
Can I order an XS439 with either clockwise or counterclockwise rotation?
Yes. Both directions are represented in the listed XS439 hydraulic pump configurations. Rotation is specified from the shaft end of the pump and must agree with the intended hydraulic drive.
Are all XS hydraulic driven pumps fitted with grooved pipe connections?
No. This page lists grooved and female NPT threaded configurations. Each has 4-inch suction and 3-inch discharge nominal ports; check the selected item number.
Can I buy replacement parts instead of a complete hydraulic pump?
Yes, individual manufacturer numbers are listed for impellers, volutes, mechanical seals, packing sets, bearings, sleeves and SAE hydraulic couplings. Request compatibility and pricing using the exact model and item number.
Which impeller fits my clockwise or counterclockwise XS439 pump?
Franklin Electric lists 305462008 for CW and 305462036 for CCW XS3x4-9 impellers. Confirm rotation and impeller trim before replacing a part.
Is the XS439 hydraulic driven centrifugal pump self-priming?
No. It is a conventional centrifugal pump. Select the appropriate priming and suction system for the installation rather than treating it as a self-priming trash pump.
What information should I send for a pump or parts quote?
Send the model, item number, SAE B/C fit, CW/CCW rotation, packed or mechanical seal, NPT or grooved port type, drive details, and requested pump or repair part numbers.
