Description & Features

The SALAMI 2.5PB32D-R87S3 pump is engineered with a 1.97 cu in/rev displacement ensuring robust performance and high efficiency. With a 2-Bolt SAE B mounting flange and 7/8 straight keyed SAE B shaft this gear pump is built for reliable and durable use in demanding industrial settings. Featuring SAE -16 side inlet and SAE -12 side outlet ports it maintains optimal fluid flow and pressure management.

Innovative floating bushings provide axial compensation promoting volumetric efficiency across the working pressure range. The continuous working pressure is rated up to 3300 PSI while peak pressures can reach 4300 PSI. The pump supports a continuous speed rating up to 3000 RPM making it suitable for high-speed applications.

Temperature resilience is assured with Buna-N seals operating between -4deg;F to 185deg;F and optional FPM seals extending the range to 230deg;F. Standard filtration recommendations adhere to ISO 4406 maintaining system cleanliness and performance. The recommended fluid viscosity range is 85 SUS to 297 SUS for optimal operation.

All SALAMI gear pumps including this model feature interchangeable components compliant with European German and American standards. This pump's clockwise rotation can be reversed for adaptable use enhancing its versatility in various hydraulic systems.

Question by: Marvin O on Nov 28, 2025, 6:51 PM
What size are the inlet and outlet ports on this thing?
Answer by: Customer Support on Nov 30, 2025, 8:13 AM
This pump uses SAE -16 side inlets and SAE -12 side outlet ports.
Question by: Earl B on Dec 14, 2025, 10:30 AM
pump says CW rotation but i need it to run counterclockwise, is that something that can be done or am i looking at the wrong unit?
Answer by: Customer Support on Dec 15, 2025, 10:49 AM
Rotation on this pump can be reversed by repositioning the drive shaft and driven shaft and rotating the front flange. So if you need CCW, you're not stuck buying a different model. It's a field-adjustable change, not a factory-only modification.
