    Triplex Sales 1-847-839-8442 www.triplexsales.com INSTALLATION PUMP INSTALLATION The installation of your Waukesha pump and its piping system should follow the practices described to give optimum performance, and be in accordance with local codes and restrictions. All system equipment, such as motors, sheaves, drive couplings, speed reducers, etc., must be properly sized to insure satisfactory operation of your Waukesha pump within its limits.

    Triplex Sales 1-847-839-8442 www.triplexsales.com INSTALLATION WARNING TO AVOID SERIOUS INJURY, DO NOT IN- STALL OR SERVICE PUMP UNLESS ALL POWER IS OFF AND LOCKED OUT. 2. Good Piping Practice. All piping to the pump should be supported independently, to minimize the forces exerted on the pump. Such forces can cause misalignment of pump parts and lead to excessive wear of rotors, bearings and shafts.
