The Milroyal has been recognized as the most reliable and robust industrial duty metering pump since its introduction. The flexibility of various liquid end designs, availability of "custom engineered" modifications, and a wide range of flows and pressure capability, the Milroyal family of pumps is capable of meeting most any application.

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

These rugged, chemical duty pumps are available in CPVC (Corzan®), fiberglass reinforced Polypropylene, and PVDF. Precision molded, dynamically balanced, "enclosed" impellers allow pumping of abrasive solutions and operating against closed discharge valves.

The D1 and DD1 are enhanced replacements of the durable SS1 series pump. The 1/8 HP motor with 1/2" diameter extended shaft and (4) precision machined pump mounting pads ensure trouble free performance for the more demanding industrial applications.
Precision molded, dynamically balanced, semi-open impellers with a unique "tandem" design allow for its ability to operate against closed discharge valves.

The C5, C7 and C8 Series pumps are designed specifically for continuous chemical duty service. They are rugged, precision molded, and feature dynamically balanced, enclosed impellers. Units are available in CPVC (Corzan®), fiberglass reinforced Polypropylene, and PVDF (Solef® ) with ratings of 1/3, 1, and 1-1/2 horsepower. The standard mechanical seal is a John Crane Type 21 single seal, carbon/ceramic. Other seal materials are available depending on the process fluid. And, water-wash seals are available for especially aggressive or "crystallizing" liquids. Pump models are also available with a rugged cast iron bearing frame for belt-drive or other coupled drivers.

Using the latest, patented pump technology, Hayward's Series R all-plastic, corrosion resistant pumps will stand up to the most aggressive, demanding industrial and commercial applications year in and year out. From the heavy duty, thick wall, glass reinforced polypropylene or ETFE pump body construction, to the rugged epoxy painted motors, there is simply no better mag drive plastic pump available anywhere. And Hayward backs every one of its Webster mag drive pumps with an extended two year warranty.
With horsepower ratings from 1/3 to 5 HP, applications requiring flow rates from 5 to 140 GPM and with maximum total dynamic head discharges up to 141 feet, you will find a Webster Magnetic Drive Pump to meet your requirements. And because the process media never contacts metal, there is never a danger of pump failure due to rust or corrosion. Because they are magnetically driven, they have no seals, thus no emissions, leaks or expensive seal replacements.

| B&G Flo-Control Valves are used for preventing gravity flow in forced water systems and to permit summer-winter operation of indirect water heaters. Flo-Control Valves in NPT sizes ¾" to 2" are made in combination straight-angle patterns permitting installation in either horizontal or vertical pipe lines. Larger sizes may be furnished in either straight or angle patterns. Removeable top cap allows easy cleaning and service without removing pipe connections. Manual operating position for vertical lift disc to permit gravity circulation. |
