Full Description

The Patay SD45 Manual Pump – This pump has been specifically designed for applications where space is limited or awkward.  Its flat back and cranked rocker arm ensures stable vertical mounting.  It is these characteristics that have made this the pump of choice for a wide range of applications such as leading Bowser manufacturers and Children’s Playground Equipment.

As we are the manufacturer of this pump,  all component parts are readily available.  No matter what you break, damage or lose, we can replace it.  No need to replace the whole pump.  How green is that?

This pump is cast in Aluminium with a removable Stainless Steel Handle.  It is available in three distinct versions:

  1. Epoxy Coated Aluminium with hand wheel access to the pump interior and stainless steel fittings.
  2. Plain Aluminium with hand wheel access to the pump interior and stainless steel fittings.
  3. Plain Aluminium with locking BZP nuts to access the pump interior and BZP fittings (As illustrated).

Note: Nitrile Diaphragms are standard. Please check your fluid compatibility before selecting other materials.
