Fluid Supply Line

See Typical Floor Mount Installation, page 12

1.Use grounded flexible, fluid supply hoses (G). See Grounding, page 8 .

2.If the inlet fluid pressure to the pump is more than 25% of the outlet working pressure, the ball check valves will not close fast enough, resulting in inefficient pump operation.

3.Excessive inlet fluid pressure also will shorten diaphragm life. Approximately 3 - 5 psi (0.02- 0.03 MPa, 0.21-0.34 bar) should be adequate for most materials.

4.For maximum suction lift (wet and dry), see Technical Data, page 20. For best results, always install the pump as close as possible to the material source.

Installation

Fluid Outlet Line

See Typical Floor Mount Installation, page 12.

1.Use grounded, flexible fluid hoses (L). See Grounding, page 8 .

2.Install a fluid drain valve (J) near the fluid outlet.

3.Install a shutoff valve (K) in the fluid outlet line.

Fluid Inlet and Outlet Ports

NOTE: Remove and reverse the manifold(s) to change the orientation of inlet or outlet port(s). Follow Torque Instructions, page 16.

1050HP — Aluminum Manifolds

The fluid inlet and outlet manifolds each have two 1 in. npt(f) or bspt threaded ports (M, N). Close off the unused port using the supplied plugs.

1050HP — Stainless Steel Manifolds

The fluid inlet and outlet manifolds each have one 1 in. npt(f) or bspt port.
