PULSAPRO Series Pumps from John Brooks Company

PULSAPRO Hydraulic Diaphragm Metering Pumps – are positive displacement, reciprocating metering pumps that combine the high efficiency of a plunger pump with the sturdiness of a diaphragm seal to eliminate leakage. They provide maximum accuracy and repeatability with the dependability of a 5-year drive train warranty. Available in a wide range of materials and diaphragm designs, these pumps offer a diverse range of fluid handling solutions. This series of pumps builds from its legendary predecessor, Pulsa Series, with expanded performance, improved robustness, and new features to simplify operation and maintenance.
