LiqflowReplacement Grinder Pumps

SHARE

The one and only grinder pump for pressure sewer systems with 20 years lifetime * and no scheduled maintenance. For the first time, it is now possible to replace an excenterscrew grinder pump directly with a centrifugal grinder pump. The OGT replacement pump comes with a mounting kit that fits directly into your excenterscrew grinder pump station. Liqflow`s Omni Grind Turbine (OGT) Pump replaces abrasive rotor and stator components with a 316 stainless steel, durable turbine impeller for delivering the one and only grinder pump for pressure sewer systems with 20 years lifetime * and no scheduled maintenance. With the use of innovative og advanced technology, the OGT grinder pump is built for continuous operation, with versatility to adapt to the current pressure in any pressure sewer systems.

Cleaner pipes with greater flexibility and lower maintenance requirements.
With a higher head up to 80 m and with a higher flow rate of up to 1.25 l/s, the OGT pump overcomes topographic challenges and friction losses in long pressure pipes while delivering superior self-cleaning speed and reducing odor and maintenance requirements throughout the pressure sewer system. Also smaller pressure pipes can be used and save establishment costs and minimize long residence times.

Low Amp technology
For continuous operation and with a 5 star energy efficient motor. Denmark`s only grinder pump for pressure sewer systems with low ampere consumption technology and a turbine impeller, provides a steep pump curve and the ability to reach a high head without damaging the pump and with reduced energy requirements while increasing lifetime operating efficiency.

Did you know:
That our OGT turbine grinder pump is the only centrifugal grinder pump in the world that can directly replace an excenterscrew grinder pump, in a existing pressure sewer system made with excenterscrew grinder pumps.

This gives you the opportunity to achieve the same reliability, as in pressure sewer system made with centrifugal grinder pumps.

Reliability- Reliability- Reliability, is the three most important factors in pressure sewer system.
  1. Abrasion Resistant Impeller. Proprietary Aerospace infusion coating technology; a stainless steel turbine impeller with multi vane design, steep curve and aerospace coating resists abrasion from sand, grit and hard particles to provide double the life of conventional Progressive Cavity pumps. This coating was used to protect the high speed turbine components in Blackhawk helicopters during the ‘Desert Storm’ conflict.
  2. Abrasion Resistant Dual Channel Volute. Has a propriety aerospace infusion coating engineered to resist abrasion for the whole of life. The Dual Channel Volute balances load on shaft which increases grinding ability.
  3. Steep Pump Curve. The steep pump curve enables smaller diameter pipework and greater control over system pressure, with capability up to 80 metres or the flexibility to set maximum limits at lower pressures providing full network control and protection.
  4. Shorter Shaft. A shorter shaft enables a closer tolerance on the cutter with tighter clearances, eliminating side-to-side deflection and jamming (as seen with progressive cavity
    pumps) while increasing the life of the mechanical seal.
  5. Slicerator. A smaller cutter and grinder radius with tighter clearances maximises cutting force for grinding fibrous materials and all modern textiles to eliminate jamming.
  6. Silicon Carbide Seal. A Silicon Carbide Mechanical Seal with vented case reduces working pressure to increase seal life. Hydraulic passages and pump-out vanes protect from
    stringy debris and abrasive media for longer life.
  7. Cable Plug. A hermetically sealed cable connector, ensures that no water will penetrate into the motor
