1. General Introduction
Milton MILROYAL B metering pump is a robust industrial duty metering pump for use in critical processes in oil and gas,chemical and hydrocarbon processes, water and waste treatment, and in most industries where chemical injection is required. The design is modular thus allowing it to accept a variety of liquid ends and other options that perfectly tune it to process requirements. Multiplex configurations provide even greater application flexibility. It mainly come with typical features as below:
u Polar crank design - all moving parts submerged in oil. Front end scavenging - The plunger always set to top dead center on each stroke..
u High Performance Diaphragm (HPD); Packed Plunger; Disc Diaphragm.
u ±1.0% over 10:1 turndown ratio.
u Maximum Performance Ratings per head is 1.1 gph (4.21 L/h) @ 10,000 psig (689 bar) to 626 gph (2,370 l/h) @ 75 psig (5 bar).
u A Manual micrometer standard Capacity Control; Electronic, pneumatic, or variable speed optional.
u Up to 8 pumps driven by one motor..
