Ask A Question

Description & Features

Designed for high-demand applications, this industrial piston pump boasts a 1.29 cu in/rev displacement. Optimal for use in mining machinery, injection molding machines, metal forming machines, oil and gas equipment, conveyor lines, primary metals, and metal cutting equipment, it provides a reliable and efficient performance.

The 2-Bolt SAE B mounting flange ensures solid installation while the 7/8 straight keyed shaft delivers robust torque transfer. Rated for a maximum operating pressure of 3000 PSI and a rated speed of 1800 RPM, this pump meets the rigorous demands of industrial settings. Its pressure compensated control (350-3000 PSI range, set to 3000 PSI) offers precise pressure management.

This pump features reduced operating noise, extended lifespan, and lower operating pressure, making it an ideal choice for systems requiring dependable and quiet operation. Vitonreg; seals and a fluid viscosity range of 80-180 SSU during running conditions ensure durability and reliability in varied environments.

Question by: Ralph T on Jul 23, 2025, 12:56 PM
pump case gotta be filled before startup or will it prime itself?
Answer by: Customer Support on Jul 25, 2025, 7:01 AM
Fill the case through the uppermost drain port with hydraulic fluid before you ever fire it up. It won't self-prime the case, and running it dry even briefly can cause real damage. Keep that case full during operation and make sure your drain line runs straight back to the reservoir and stays submerged below the oil level.
