Barnant Hose
Pumps Type PA

The PA and PAX series are comprised of 4 different models. Their rugged cast housing and integrated gear box provide a small compact footprint ideal for many OEM applications.

This series offers the dry running design, which provides long tubing life, yet prevents system contamination should the hose ever rupture.

Flow capacities to 12 GPM single hose.


The hose design allows easy hose replacement without disassembly of the pump. The tube bed is designed with two flanges that prevent side to side movements of the hose.

These pumps are shipped as complete pump, motor, drive systems ready to install and start up. Standard motor drives are fixed speed.


Optional drives include:
• Mechanical variable speed

The standard inlet and outlet connections provided are barbed hose type. Optional inlet and outlet connections available include ANSI 150# flanges, Sanitary Tri-Clamp fittings, and NPT connections.

Characteristic Lines

The pump characteristics give approximate values for the conveying capacities at various pressures. They are related to the pumping of water. For materials with higher viscosities lower capacities are to be expected. Speed range <100 min-1 is suitable for continuous operation of the pump. Speed range >100 min-1 is suitable for short-time operation of the pump.
