Engineered for Multiple Power Inputs

Water Truck Pumps

Robust centrifugal pump solutions built for the water truck industry.
In the field, every pump decision comes down to two factors:

  • The conditions on the jobsite and the water demand at hand.
  • How power is supplied to move water efficiently and reliably.

Demand is shaped by the environment. Pump performance is shaped by power transmission.

PTO Drive

Compact gear-driven pump for mechanical PTO shaft applications. Proven in demanding field conditions.

Hydraulic Drive

Variable speed hydraulic pump using the ARMS core platform — simplifying fleet service and parts inventory.

SAE Engine Drive

Direct flywheel-mounted configuration delivering maximum torque for the heaviest-duty applications.

Self-Prime

Primes without manual intervention — restarts quickly even after running dry in remote field conditions.

PTO Drive

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.

  • Frame MountedCompact design mounts directly to truck frame for a clean, stable installation.
  • CCW & CW RotationAvailable in both counter-clockwise and clockwise configurations to match your drive setup.
  • Mechanical Seal or PackingChoose the seal type that best suits your application and maintenance preference.
  • Victaulic & Threaded ConnectionsMultiple connection options to fit your existing plumbing configuration.

Hydraulic Drive

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.

  • Variable Speed OperationHydraulic drive allows flow rate adjustment without stopping — ideal for jobsite flexibility.
  • SAE-B 2-Hole MountDirect hydraulic motor mounting for a clean, compact installation on your truck.
  • Shared PlatformCross-compatible parts with PTO lineup reduces your spare parts inventory.
  • Victaulic, Threaded & GroovedMultiple connection types available including grooved for quick-couple systems.

SAE Engine Drive

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.

  • SAE-4 Flywheel MountDirect engine-mounted configuration eliminates coupling components for maximum efficiency.
  • Double-Row Front BearingHeavy-duty bearing handles the elevated radial loads of direct engine mounting.
  • Flanged & Victaulic ConnectionsAvailable in 6×4 flanged and 4×3" Victaulic configurations.
  • Keyed Shaft OptionShort shaft extension with keyed input available for specific mounting requirements.

Self-Prime

Self-Prime Pump

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.

  • No Manual PrimingSelf-primes automatically — no intervention required after running dry.
  • Fast RestartQuickly re-primes in the field between fills, keeping operations moving without downtime.
  • Remote Jobsite ReadyIdeal for applications far from reliable water sources where manual priming is impractical.
  • High PerformanceFull centrifugal pump performance once primed — no flow or pressure compromise.

Know Before You Buy

Standard vs Premium Series

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.

Standard Pump
Standard Series

Efficient. Affordable. Field-Ready.

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.

  • Compact Lightweight Power Frame Reduced system weight — ideal for bobtail configurations
  • 7-Vane High-Efficiency Impeller Aggressive hydraulic performance with excellent responsiveness and operating efficiency
  • Suited for 2,000-Gal Bobtail Trucks Right-sized for general-purpose water distribution applications
  • Quick Replacement Ready Interchangeable with many pumps in its performance class — minimal downtime
  • Affordable & Serviceable Balanced combination of cost, reliability, and ease of field service
VS
Premium Pump
Premium Series

Severe-Duty. Maximum Volume. Built to Last.

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.

  • Heavy-Duty Reinforced Discharge Connection Engineered for high vibration, torsional loading, and continuous operation
  • Large Maximum-Volume Impeller Robust design built for peak flow output in the most demanding conditions
  • Enhanced Structural Rigidity Upgraded connection architecture for long-term durability under rugged field use
  • Extended Service Life Designed for water truck, construction, industrial, and heavy fleet environments
  • Superior Mechanical Strength Built for operators who demand maximum uptime and enhanced structural integrity
