Description & Features

This cast iron gear pump boasts a displacement of 2.10 cubic inches per revolution. Engineered for high performance it features a 2/4-Bolt SAE B mounting flange and a 13T splined shaft measuring 1.61 inches in length. The side inlet and outlet ports are designed with SAE -16 and SAE -12 specifications respectively. Its clockwise rotation suits a variety of industrial applications.

The pump is manufactured by Salami S.p.A and is known for its high volumetric efficiency thanks to innovative design and precise machining tolerances. The use of floating bushings for axial compensation ensures consistent efficiency across the working pressure range. The unit supports a continuous pressure rating of up to 4000 PSI and peak pressures up to 4350 PSI.

Adaptable to European German and American standards the pump allows flexibility in shaft flange and port options. The recommended fluids range from 66 SUS to 3635 SUS in viscosity providing a broad operational spectrum. The temperature tolerance ranges from -4deg;F to 230deg;F depending on seal type.

Question by: Donna W on Aug 22, 2025, 7:50 PM
clockwise rotation only on this one, or can it be flipped to run CCW if needed?
Answer by: Customer Support on Aug 23, 2025, 9:09 PM
Rotation can actually be changed on these pumps by reversing the position of the drive shaft and driven shaft and rotating the front flange. It ships standard with clockwise rotation, but you're not locked into that if your setup calls for something different.
