Pump Input Shaft Details

Accu-Staltic pump rotors are built and stocked standard with shaft ends 1 and 2 shown below for maximum flexibility. A rotor can be easily installed for right- or left-hand drive needs.

If these options do not suit your needs, a preferable alternative to a custom shaft may be the Shaft Extension Kit. This converts shaft end '1' to a 1", ¼" keyed shaft, for easy application of a coupler, or for ganging multiple pumps together. custom diameters can easily be machined.

Shaft ends:

Female End: for applications powered by a hydraulic motor that use a 4-hole square mount similar to a CharLynn motor with a 1" dia. by 1.68" long shaft. Transition plate provided to direct-mount motor to pump.

Male end, Standard configuration for non-driven shaft ends, or where the end installtion will require a coupler. Provided with .375" bore to receive rotary encoder shafts and # 806 woodruff key (1/4" x 3/4") for secure coupler attachment.

If the motor has adequate torque, 2 or more pumps can be mechanically coupled and driven together. If you desire to do this, order a 'left' and a 'right' configured pump for ease of coupling.

Instructions for 1 inch shaft adapter, for use with Accu-Staltic™CP5125XX series, 1.25" hollow-bored shaft pumps.

This adapter is for use with our standard hollow-bored 1.25" shaft pumps, models CP5125xx, with the x's being the number of channels.

The Kit includes 3 pieces:

Cut the shaft and deburr it to the necessary length to fit a Lovejoy or other style coupling inside the motor mounting bracket that you will need to fabricate (not included). Four, 5/16-18 threaded mount holes are provided on the pump endplates, spaced at the corners of a 3.5" square, concentric to the shaft.

Slide the clamping collar over the 1.25" shaft so that the split on the collar and the split on the shaft are lined up, and there is just enough room to tighten the set screw.
