Engineered for Multiple Power Inputs
Robust centrifugal pump solutions built for the water truck industry.
In the field, every pump decision comes down to two factors:
Demand is shaped by the environment. Pump performance is shaped by power transmission.
Compact gear-driven pump for mechanical PTO shaft applications. Proven in demanding field conditions.
Variable speed hydraulic pump using the ARMS core platform — simplifying fleet service and parts inventory.
Direct flywheel-mounted configuration delivering maximum torque for the heaviest-duty applications.
Primes without manual intervention — restarts quickly even after running dry in remote field conditions.
PTO Drive
Compact • Gear-Driven • Reliable
Ideal for mechanical PTO shaft drives, our frame-mounted PTO pumps are engineered for demanding field conditions with a compact footprint that keeps you running shift after shift. Available in both CCW and CW rotation with mechanical seal or packing configurations.
Hydraulic Drive
Variable Speed • Fleet Ready • Durable
Uses the same ARMS core platform as our PTO lineup — reducing your parts inventory and simplifying service across your entire fleet. Hydraulic drive pumps offer variable speed capability and are available with SAE-B 2-hole mounting for direct hydraulic motor integration.
SAE Engine Drive
High Torque • Heavy Duty • Direct Drive
Direct SAE flywheel-mounted configuration delivers maximum torque transfer for the most demanding heavy-duty water truck applications. The flywheel mount eliminates coupling components and provides a rigid, vibration-resistant connection directly to the engine.
Self-Prime
Self-Priming • High Performance • Field Ready
Designed to prime itself without manual intervention — ideal for water truck applications where the pump runs dry between fills or needs to restart quickly in the field. Eliminates the delays and hassle of manual priming on remote jobsites.
Know Before You Buy
Both series are built from fully machined high-grade aluminum. The difference comes down to frame size, discharge connection design, impeller volume, and the environment they're built for. Use this as a starting point — our team can match the right series to your application.
Engineered for cost-effective performance without cutting corners. The Standard Series uses a compact, lightweight power frame with a conventional discharge connection — keeping overall system weight down while delivering dependable output. When a pump goes down on the job, this is the one you swap in fast and get back to work.
Built for operators who can't afford failure. The Premium Series was engineered specifically for severe-duty environments and high-demand jobsite conditions where maximum durability and structural rigidity are non-negotiable. From construction fleets to industrial operations, this is the pump built to outlast the job.
