Oilgear_Towler_Pump_PFBA-2-2

A compact, high-pressure, dual-discharge pump.

The PFBA pump has proved itself successful for use with high water content and low-viscosity fluids. These axial piston pumps are used in a wide variety of applications, including die casting and injection molding machines, high pressure test rigs, civil and marine projects, intensifier systems, extrusion presses, forging presses and high pressure forced lubrication systems for long turbines as well as metal forming machines.

Oilgear makes some of the longest-lasting, most reliable pumps in the world.  The PFBA pump is from the Towler high-pressure pump product line that specializes in extreme reliability when pumping low-viscocity fluids, such as water-based fluids.

The PFBA-2/2 has two, high-pressure discharge port.

The PFBA swashmember 13° angle results in low piston head loading, allowing for high speed operation and compatibility with high pressure and high shock loads.  A polymer coated plate is attached to the swashmember to provide a bearing surface for thrust loads.  The six hardened steel pistons located in a stationary body are not subject to centrifugal force, thus reducing load and wear. The piston load is caused by pumping action only, therefore higher operating speeds are possible.  The optional, built-in supercharge pump lubricates and provides case flow for cooling the main pump and eliminates the need for an external supercharge pump.

All Oilgear pumps are designed to thrive on low-viscosity fluids, such as high water content and fire resistant fluids, like Skydrol™, Stack Magic™, Erifon™, and 98/2.  Learn more here:  Fluid Compatibility of Oilgear Pumps.
