G Hydraulically Actuated Diaphragm Liquid Ends

Economical and robust, the Milroyal G pumps dose all traditional liquids used in water treatment and industrial processes including: acids, bases, chlorinated products, coagulants, and other products. Designed for ease of maintenance and start-up, the Milroyal G features a robust HPD-style hydraulically actuated diaphragm liquid end coupled to a 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 integral 3-function 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 site glass 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.

Product Features

  • HPD liquid end design eliminates contour plates.
  • Double diaphragm w/leak detection available (10/98).
  • Liquid End Materials: PVC, PVDF, 316SS.
  • High viscosity and slurry liquid end options.
  • 56C face and IEC motor options
  • Integral 3-function valve in hydraulic oil system: automatic airbleed, safety/relief valve, purge button.
  • Non-lost motion drive design minimizes flow pulsations and mechanical shock.
  • AC & DC variable speed drives available for automatic control from a 4 – 20 ma signal.
  • Recommended Service Intervals: 8000 hours when operating at full rated pressure

Availability:

  • Frame 1 – Available now
  • Frame 2 – Available now

D Series Metering Pumps

Mechanically Actuated Diaphragm (MAD) Liquid Ends

Economical and robust, the MacRoyTM series metering pumps dose all traditional liquids used in water treatment and industrial processes including: acids, bases, chlorinated products, coagulants, and other products. They feature a cost-effective mechanically actuated diaphragm liquid end that eliminates the risk of hydraulic oil contamination in the even of a diaphragm rupture. The absence of contour plates in this liquid end results in “straight-thru” flow ideal for handling polymers and slurries.
