Metering Pumps - Plunger Type
Metering Pumps - Plunger Type
TRANSFLO™ Metering Pumps are high precision positive displacement pumps, as per API 675 code. The discharge can be varied from zero to 100% capacity while pumps are running. Metering Pump capacity is almost independent of the discharge pressure. PLUNGER TYPE METERING PUMPS - Plunger Pump Heads are a good choice for simple applications with non-critical, harmless fluids.

Working Principle:

The reciprocating plunger directly displaces the process liquids. Axial shifting of the skew slotted sliding shaft radically shifts the variable eccentric. The stroke length of the crank shaft correspondingly changes. A reproducible setting from zero to maximum stroke length is possible. As the plunger and plunger seals are coming in contact with process liquid, the best performance for the application is achieved by optimal selection of plunger material. Plunger Pump Heads are a good choice for simple applications with non-critical, harmless fluids.
