DIGESTER FEED PUMPS

Digester Feed Pumps

No More Clogged Pump or Piping

The EMS Ram Pump – pumps what others can’t (rotary lobe, progressive cavity, piston membrane, air diaphragm, etc.).

Feedstock: EVERYTHING including Food and Drink Waste, Agricultural Residues/Manures, Crops, Process Residues (Bakery and Brewery Waste, etc.) Sewage Sludge, or any combination thereof.

Bring it on! If it can be sucked in, we can pump it out!

Flow Range: 23-300 gpm (90-1200 liters/minute)
Discharge Pressures: 0-436 psi (0-30 bar)
Suction Lift: up to 30 Feet (9 meters)

Tungsten carbide coated ram and special “double ball checks” that really “check”.

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.

VRM PUMP FEATURES

Suitable for continuous use 24/7
Slow speed, quiet operation
Huge suction draws thick sludge up to 15%ds
Simple construction
Up to 50m (165 ft) delivery head
Up to 6.5 lit/sec (103 gpm)
Minimal maintenance

Pump Capabilities

Flow Rates: 15-475 GPM /(3-108 m3/hr)
Suction Lift: 9 meters /(30 feet)
