Installing plumbing

When you finish mounting your pump on a motor, you must install the plumbing for the pump. Follow these steps after you have mounted your pump.

1. Install the inlet and outlet fittings

   • Support the pump by using a backup wrench on the square port bosses. Do not put any strain on the V-band clamp.

   • Use brass fittings or plastic fittings on a brass pump. Use stainless steel or plastic fittings on a stainless steel pump. Using dissimilar metals can cause corrosion, which may get into the pump and cause damage.

   • Use Teflon thread tape to install the fittings. Do not let any thread tape get into the pump and do not over- tighten the fittings

2. Check the inlet line

   • Make sure the inlet line is big enough to allow adequate flow to the inlet port of the pump (3/8 inch internal diameter for series 1, 2, and 3; 1/2 inch internal diameter for series 4 and 5; 1 inch internal diameter for the series 6; all elevated temperature applications above 150 degrees Fahrenheit must have oversized inlet piping).

   • Make sure the inlet line is clean and properly flushed out. Protect the pump with a 100 mesh or liner strainer or filter.

3. Connect the inlet line to the fitting on the pump

4. Connect the outlet line to the fitting on the pump
