Liberty Pumps has the ability to design custom systems for your development project. Whether simplex, duplex, triplex or quadplex, you can select from a wide array of basin sizes, discharge heights and control panel options. 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. 5 -10 0 200 190 180 170 160 150 140 130 Li- 120 -0 110 I 100 . _ E 90 co ). 80 Ct 3, 70 60 52 (6isd) - Hal 43 35 87 78 69 61 26 17 9 15 20 25 30 35 40 45 Gallons Per Minute 50 40 30 20 10 0 -41 ;lit! 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. Omnivore ° 2-stage performance curve LSGX-Series 2 hp 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.
