NOBODY CAN TOUCH OUR CURVE.

Environment One’s semi-positive displacement, progressing cavity pump has a nearly vertical H-Q curve. It is by far the most “forgiving” pump design – providing predictable flow over the full range of typical system pressures; strengths critical in a large-scale, low-pressure sewer.

Motor
1 hp, 1,425 rpm, high torque, capacitor start, thermally protected, 120/240 V, 50 Hz, 1phase


Discharge Connections
Pump discharge terminates in 32 mm female solvent weld fitting; the threaded adapter is supplied and discharge can easily be adapted to 32 mm NPT.


Discharge
56.7 lpm at 0 bar (0.95 lps at 0 m)
41.6 lpm at 2.7 bar (0.69 lps at 28 m)
29.5 lpm at 5.5 bar (0.49 lps at 56 m)

The Upgrade grinder pump is engineered to fit into virtually any grinder pump wetwell. Universal design allows easy drop-in conversion, ready to connect. The Upgrade is a complete replacement for all of the troublesome components of a centrifugal pump station, including the old unit’s slide rails, pump/moptor, float switches, piping, and motor control devices.


• Designed not to jam and for minimum wear to the grinding mechanism


• Retrofit simplex or larger stations


• Available with a range of discharge hose lengths to accommodate a wide range of tank depths


The Upgrade comes complete with a self-contained level control system, eliminating troublesome float switches. The internal check valve assembly located on the grinder pump is custom designed for non-clog, trouble-free operation. The Upgrade uses E/One’s “hardwired,” or “wired,” pump model where a cable connects the motor controls to the level controls through watertight penetrations.

10 REASONS TO SWITCH TO THE E/ONE UPGRADE

E/One Pump

  1. Semi-positive displacement pump -  provides virtually the same flow regardless of pressure. Scouring velocities are maintained without stressing the pump.

  2. Non-jamming grinder – low-speed, high-torque, with the large-diameter inlet.

  3. Non-contact, non-fouling pressure switch level controls. Proven reliable and maintenance-free.

  4. Air-filled motor requires zero preventive maintenance.

  5. Built-in check valve and anti-siphon valve.

  6. Longest mean time between service calls – 10 years.

  7. Lowest operation and maintenance costs.

  8. All pump, level, and motor controls in one compact assembly, making service simple and convenient.

  9. Near-constant flow regardless of pressure – prevents a build-up of solids in piping.

  10. Zero preventive maintenance.

Other Grinder Pump

  1. Centrifugal pumps – flows vary dramatically, causing high flows and dangerously short run times to no flow and continuous operation. The result: burned-out motors.

  2. Jamming common – high-speed, low-torque, with a small-diameter inlet.

  3. Float switches – require preventive maintenance to remove grease and oil. A constant source of problems. Mercury float switches difficult to dispose of are an environmental issue.

  4. Oil-filled motor requires periodic oil changes.

  5. No anti-siphon valve.

  6. Constant service calls

  7. Routine preventive maintenance and service calls

  8. Separate pump, level, and motor controls making troubleshooting and repairs more difficult and time-consuming

  9. Widely varying flow reduced as
    pressure increases, allowing
    a build-up of solids in a pipe. Solids build-up causes increased pressure and reduced flow, compounding the problem.

  10. Jammed grinders, grease-
    fouled floats require periodic
    maintenance.

PUMP INLET

Environment One

(133mm) 5.25” inlet

Inlet Velocity 3.6 ft/sec (1.6 m/sec)

Other Grinder Pumps

(63mm)2.5” inlet

Inlet Velocity 22.8 ft/sec (6.95 m/sec)

Electrical Quick Disconnect (EQD)

The progressing cavity pump itself is based on the Moineau principle. A rotor turns within a stator, creating a sequence of sealed chambers. The precision-cast and polished stainless steel rotor move wastewater through these chambers at a nearly constant flow, over a wide range of conditions – from negative to abnormally high heads. Turning at just 1,425 rpm, the one-horsepower motor can pump fluid through more than three kilometers of small-diameter piping or elevation changes of over 56 meters.

SOME KEY ADVANTAGES:

HIGH HEADS/NEGATIVE HEADS.

Reliable operation from a negative head to 56 meters of total dynamic head for continuous duty reduces the number of lift stations and pipe sizes. This cuts costs – both initially and in long-term operation and maintenance.

CONSTANT FLOW.

The system pressures to be overcome by any given grinder pump in a low-pressure system vary dramatically over the course of a day. E/One’s progressing cavity pump readily accommodates these pressure variations while maintaining a nearly constant flow without ever operating at “near shut off” – thus avoiding the wear and motor burn-out suffered by other pump types.

HIGH GRINDING TORQUE.

Our unique pump system, driven by a one-horsepower motor turning at 1425 rpm, produces grinding torque greater than a two-horsepower pump turning at twice the speed.

ENERGY EFFICIENT.

The pump is activated automatically and runs for short periods. Typical annual energy consumption is comparable to a 40-watt light bulb.

LOW MAINTENANCE SUBMERSIBLE MOTOR.

Low maintenance and long life are the hallmarks of our air-filled motor. Permanently lubricated ball bearings and Class F insulation eliminate the need for periodic oil changes and oil disposal costs required by oil-filled submersible motors.

LARGE-DIAMETER GRINDER ASSEMBLY.

Almost twice the diameter of most other types of grinder pumps, contributing to a dramatic reduction of inflow velocity for less wear and no blinding, clogging or jamming.

NO PREVENTIVE MAINTENANCE.

Non-fouling static level sensors require no preventive maintenance. Because of our unique, near constant discharge rate,
no mainline flushing is required in a properly designed system.

CORROSION RESISTANCE.

E/One’s stainless steel ball-type discharge valve and piping won’t corrode like copper or galvanized, and hold up years longer. No corrosion, no maintenance.

DEPENDABILITY.

E/One pumps typically run ten years between service calls with 40 years of in-ground experience.

PROVIDES FOR ENVIRONMENTALLY SOUND WASTEWATER MANAGEMENT.

The E/One Extreme Series grinds waste material into small particles. This enables the use of inexpensive, small-diameter pressure pipes, buried at shallow depths, to transport wastewater to a suitable processing site. Result: Groundwater contamination from failing septic tanks can be eliminated.

SERVICEABILITY.

Our unique core design eliminates the need for in-field troubleshooting and pump servicing. This means lower maintenance costs and minimum homeowner inconvenience.
