LSGX-Series, Omnivore™ X2, 2-Stage High Head Submersible Grinder Pumps

Unleash the power and reliability of the Omnivore - with patented V-Slice Cutter technology.  Now you have the power to build anywhere.

Omnivore LSGX-Series 2-stage grinders provide economical answers for difficult building sites. With proven V-SliceTM cutter technology, the Omnivore macerates sanitary waste into a fine slurry allowing it to be pumped through small diameter pipe — eliminating costly gravity systems with larger pipe and deep trenching. Now, engineers, housing developers and land design planners have the freedom to replace restrictive gravity-style systems with cost-effective, Omnivore driven low pressure sewers.

• Lower installation cost with smaller diameter pressure pipe
• High-head capability reduces the need for costly lift stations
• Superior pump design allows for efficient pumping over a wide range of head applications – even negative head.
• Efficient design provides lower operating cost
• Unsurpassed reliability reduces maintenance and homeowner inconvenience

  The power to meet high-head requirements — now in a centrifugal pump design.

With literally thousands of Omnivore grinders installed across North America, the proven design of Liberty’s LSG-Series has been taken to new heights with the new 2-stage LSGX-Series. Now with twin stainless steel impellers driving flow to maximum heads of over 180 feet, the LSGX can be installed in applications where traditional progressive cavity style pumps have been required. Now get the superior cutting of patented V-SliceTM technology with pumping performance that rivals traditional progressive cavity style pumps.

• Better cutting
• No rotor/stator wear
• Same pressure, more flow
• Greater reliability

Patented V-Slice Technology Provides in excess of 370,00 cuts per minute. Superior cutting system provides improved shredding performance over radial cutters. V-pattern provides up to 108 alternated cuts per revolution. Entire cutting system made of 440 stainless steel hardened to 58 Rc. Robust performance over a wide range of heads.

The LSGX-Series curve provides superior flows over a wide range of typical pressures — necessary for multi-unit developments and “large-area” low pressure sewer systems. The 2-stage LSGX-Series now allows installation of a centrifugal design where progressive cavity style pumps have traditionally been installed.

Liberty Pumps LSGX-Series 2 hp Grinders are available both Manual and Automatic:

•  Manual - means that the pump is provided less an automatic switch assembly
•  Automatic - models include a wide angle float switch with piggy back (series) plug

Engineered Pump Systems – EPS

As a distributor for Liberty Pumps we have the ability to design custom systems for your development project. Whether simplex or duplex, you can select from a wide array of basin sizes, discharge heights, voltages, control panels and even custom options.

Omnivore Interchangeability

You choose — single-stage or 2-stage. Not all applications have the same hydraulic requirements. Since both LSG single-stage and LSGX 2-stage grinder pumps use the same platform and guide rail system, the right pump can be chosen for the individual application, depending on your topography.
Complete interchangeability is available with the Omnivore family of grinders. A single-stage Omnivore can be pulled and directly replaced
with a 2-stage, all within the same basin and guide rail setup — providing total flexibility.

Superior Hydraulics

Many benefits come with the use of centrifugal impellers instead of positive displacement stators. Many of the maintenance issues are eliminated, such as dry start, clogging and boot failure. Also, centrifugal impellers have the ability of flow control. When multiple units are competing for space in the same sewer main, the centrifugal design enables pumps to seek the optimum flow without accumulating pressure and causing pipe or boot failure.
