1. Introduction

PULSAR Shadow

metering pumps are positive displacement reciprocating pumps. They

combine the high efficiency of the plunger pump with diaphragm sealing to prevent product

leakage. Each pump consists of a power end and a process end separated by a mechanically

operated diaphragm. Individual pumps will vary in appearance due to various liquid ends,

accessories, and multiplexing; however, the basic principles of operation remain the same.

1.1 Overall Operation

Figure 1

A diaphragm reciprocates at a preset stroke length, displacing an exact volume of process fluid.

Diaphragm retraction causes the product to enter through the suction check valve. Diaphragm

advance causes the discharge of an equal amount of the product through the discharge check

valve.
