1. General Introduction

Milton Roy mROY series metering pump is a controlled-volume, hydraulically-actuated diaphragm pumps that designed for consistent chemical delivery. Its compact design contains a plunger that reciprocates at a fixed stroke, displacing a fixed volume of hydraulic fluid and thereby actuating a flexible, chemically inert PTFE diaphragm to create the pumping action. This field-proven design enables metering with repetitive steady-state accuracy at a ±1% range. There are two models A and B, provide accurate dosing of a broad spectrum of fluids, both types are built to run continually all year long with preventative maintenance, leading to decades of consistent performance. It mainly come with typical features as below:

u Hydraulically-balanced PTFE diaphragm, designed for 96,000 hours operating life, does not use seals and eliminates plunger packing maintenance.

u Liquid end bleed system makes it easier to commission a new or a newly maintained pump.

u Worm and pinion drive operating in an oil bath lubrication produces a smooth mechanical motion that eliminates wear and tear of mechanical lost motion designs and assures long gear and bearing life.

u Dust-tight cast iron housing provides a rugged enclosure for operation in the harshest plant and field environments.

u Micrometer capacity adjustment enables accurate output flow control.

u Internal hydraulic pressure relief valve automatically protects the pump’s hydraulic system from over pressure conditions.

u High-performance, adjustable, cartridge-type check valves provide positive, repeatable sealing on every pump stroke.
