New features

The mROY pump includes new features for enhanced safety, improved hydraulic efficiency, easier start-up and maintenance. The pump's housing and liquid-end materials deliver steady-state accuracy of ±1.0% over a 10:1 turndown ratio to ensure precise delivery of critical or difficult fluids. The metering pump provides flow ranges from 0.20 gph (0.8 l/hr) up to 87 gph (330 l/hr) in a simplex configuration. 

Milton Roy says that the pump remains proven in hundreds of thousands of installations worldwide with some pumps operating at design performance for 20 years or more.

It also boasts a three-year warranty along with a hydraulically balanced diaphragm for 96,000 hour design life.
