Metering Pumps | Primeroyal PL Model

The PRIMEROYAL L (PL) metering pumps are built to deliver consistent and accurate dosing for a wide variety of fluids at pressures up to 14,996 psi (1,034 bar) and a maximum flow rate of up to 1,164 gph (4,410 l/h) per dosing head. With proven ±1% steady-state accuracy and a robust, compact eccentric drive system, the PL pumps provide dependable operation from 10% to 100% of nominal flow. Thanks to their modular construction and multiple choice of liquid ends, the PL series pumps are perfect for industries needing flexibility without compromising on precision.
