MILROYAL G METERING PUMPS
Hydraulically Actuated Diaphragm Liquid End
The robust Milroyal GTM metering pump doses all traditional liquids used in
water treatment and industrial processes including: acids, bases, coagulants,
chlorinated products, and many others. Designed for ease of maintenance
and start-up, the Milroyal G features Milton Roy’ advanced hydraulically
s
actuated High Performance Diaphragm (HPD) liquid end coupled to a durable
variable eccentric drive. The absence of contour plates in this liquid end
results in “
straight-thru”flow ideal for handling polymers and slurries. A
unique tri-mode hydraulic system valve allows for purging of any entrapped
gases in the hydraulic oil without disturbing the relief valve setting. Also
integral to the liquid end is a view port for visual indication of a relief condition
in the hydraulic system. The smooth sinusoidal flow produced by the variable
eccentric drive minimizes flow pulsations and mechanical shock to system
components.
