These pumps are positive displacement devices capable of generating high line pressure. Discharge lines should be fitted with properly sized line pressure relief valves to protect both the pump and the system. The relief outlet should be piped back to the suction vessel.
LIQUIDS & TEMPERATURES
Tailored to handle typical processing conditions including raw sap to 220F up to 80 psi as well as 140F hot water flushing. Regreasing is recommended to prevent sap build-up between shaft and bearing surfaces.
*For pressures over 100 psi, the above selections are suitable for pumping fluids with lubricity (e.q. oils, polymers). Service life will decrease for fluids without lubricity (e.q. water, solvents).
Close tolerances and positive displacement action make the rotary gear pump capable of lifting fluid on the suction side as high as 20 feet. Though gears pumps are self priming, a foot valve is recommended. If possible, wet the gears with liquid to be pumped for the first dry start. Liquid retained in the system and gear chambers serves to "wet" the pump on subsequent starts.
