Question by: Scott B on May 20, 2025, 12:39 PM
Running a dump truck setup and need to confirm the rotation before I order. This one's CCW, right, and the shaft's that 1-1/2 straight keyed style?
Answer by: Customer Support on May 22, 2025, 7:14 AM
CCW rotation is correct, and yes, the shaft is a 1-1/2 straight keyed configuration. Worth double-checking your drive coupling before you bolt it up, since pairing this with a CW-rotation power source will cause problems right out of the gate. The mounting flange is a 2-bolt SAE C, so make sure your adapter plate or bell housing matches that pattern before the pump arrives.

I need a new pump for my dump truck, and this one says it's good for that. How long can I run it at the max pressure without causing problems?
Answer by: Customer Support on Oct 16, 2025, 12:01 PM
Designed for high-pressure and high-speed applications, this 45VQ series vane pump can handle the 2500 PSI maximum pressure. However, continuous operation at the maximum pressure can reduce the pump's lifespan. For optimal performance and longevity, it's best to operate within the recommended pressure ranges for your specific dump truck application.
