Operating Viscosities:

For petroleum-based fluids the optimal level is 150 SUS. For continuous operations, the level should range from 60 to 5000 SUS.

Filtration:

A minimum of 10 micron (abs.) filtration is required. A return line filter is preferred. Bypass filtration and suction filters/ strainers are not recommended. Fluid cleanliness should conform to ISO 16/13 level.

Inlet Conditions and Piping:

The maximum temperature at the inlet should be 140º F. For higher levels consult factory. Inlet pipe, hose or tubing must be sized properly to limit resistance to < 6 in. Hg (3 psi). Suction hose, if used, must be wire reinforced to prevent its collapse. All connections must be air-tight.

Case Drain:

Two case-drain ports are provided on all models. The case-drain line must be properly sized to limit port back-pressure to < 25 psi.

Tandem Pumps:

All side-ported models can be modified to tandem pumps by adding a thru-drive shaft and a coupling. In addition, adapter flanges can increase or reduce flange pilots. Consult factory for details.

Pump approximate weight: 200 lbs.
