EMS Ram Pumps

RAM Pumps by EMS

Filter Press Feed Pumps/Grit Removal/Primary Sludge Transfer Pumps/Food Waste Pumps

Often referred to as plunger, reciprocating or piston pumps, EMS RAM PUMPS offer a greater suction lift for dredging and pumping sewage, waste water, filter press feed, backwash and grout or effluent.

The Positive Displacement EMS RAM PUMPS are robustly designed and constructed of S.G. iron castings with stainless steel features for the most aggressive environments. Our PUMPS are available in a variety of materials to address “target applications” of grit & sand removal, dredging, grout pumping, primary sludge transfer, filter press feed, kaolin and clay pumping.

HYDRAULIC PUMPS

The heavy duty, hydraulically-driven VRH is the most powerful pump in the range. Available in sizes shown above, the VRH line of EMS RAM PUMPS is suitable for pumping high solids viscous material and features large gravity ball type sludge check valves.

VRH PUMP FEATURES

Ideal for heavy duty sludge transfer
Tungsten carbide coated sludge ram
Suitable for continuous use
Slow speed operation
Huge suction draws thick sludge
Numerous hydraulic and electronic control designs & options
Up to 500m delivery head
Up to 30 lit/sec flow
Minimal maintenance
Duplex and triplex options with near laminar flow

MECHANICAL PUMPS

The mechanically-driven VRM is one of the most popular pumps in the range. The mechanical arrangement features vee belts, a reduction gearbox and a crankshaft final drive providing a basic, simple to understand driveline. VRM Pumps are available in various sizes.

Sludge non-return valves come in various designs and can be positioned in-line or at right angles to each other allowing the pump to be installed in tight spaces. All VRM pumps create a suction vacuum equivalent to 9 meters (30 ft) static suction lift.
