PAUTER CENTERFLO PUMPS

   
The gerotor pump with a real difference!

In this innovative redesign of the popular gerotor style pumping mechanism, Pauter Machine has done away with the old style feeder plates with their restrictive right angle entry/exit ports. The result is a cleaner, more efficient design, with improved performance on both the scavenge and pressure sides. The above pumps, a single stage with fuel pump adapter on the back, and a four-stage (one pressure, three scavenge stages with optional manifold) are both setup for cam-drive system for the air-cooled VW but are also available with belt-drive and remote mount universal bracket for other applications. All pump body parts are CNC machined 6061-T6 aluminum, hard anodized for wear resistance and surface protection. Internal working parts (shafts, gerotor units) are steel.

Pauter manufactures their own belt-drive compatible drives in a number of ratios, as well as 3-into-1 manifolds to simplify pressure side plumbing setup. All parts are CNC machined hard anodized 6061-T6 aluminum. Pump rotation is at the owner's option, but inlet/outlet plumbing switches relative to rotation.

Gear and rotor are 1.10" width  by 2.625" diameter.

A closer look at the heart of our pumps; the specially modified rotor unit. The ports at the rotor nodes allow direct access to the inner workings of the pump. When coordinated with the proper body porting, this arrangement simplifies the oil path both into and out of the pump. Significant gains in scavenge vacuum and in low rpm pressure development are produced. Our improvements aside, the basic gerotor design was chosen as our starting point as it offers advantages over the common spur gear design that could not be ignored. In particular, running clearances are self minimized by the interaction of the parts during normal operation, and wear is focused on the more resistant steel components.  Call to discuss your requirements and available configurations.
