Features
All solids are ground into fine particles, allowing them to pass easily through the pump, check valve and small diameter pipelines. Even objects that are not normally found in sewage, such as plastic, rubber, fiber, wood, etc., are ground into fine particles.
The grinder is designed not to jam and for minimum wear to the grinding mechanism. The Upgrade comes complete with a self-contained level control system, eliminating troublesome float switches. The grinder pump is automatically activated. It runs infrequently for very short periods. The annual energy consumption is typically that of a 40-watt light bulb.
The 1 1/4" slide face discharge connection is adaptable to any existing discharge piping.
The internal check valve assembly, located on the grinder pump, is custom designed for non-clog, trouble-free operation.
Units are available with a number of discharge hose lengths to accommodate a wide range of existing tank depths.
Operational Information
Motor
1 HP, 1725 rpm, high torque, capacitor start, thermally protected, 240 or 120 volt, 60 hertz, 1 phase
Inlet Connections
4" inlet grommet standard for DWV pipe. Other inlet configurations available from factory.
Discharge Connections
Pump discharge terminates in 1-1/4" NPT female thread. Can easily be adapted to 1-1/4" PVC pipe or any other material required by local codes.
Discharge*
15 gpm at 0 psig
11 gpm at 40 psig
7.8 gpm at 80 psig
Overload Capacity
Maximum pressure that the pump can generate is limited by motor characteristics to a value well below the rating of the piping and appurtenances. Automatic reset feature does not require manual operation following overload.
US and foreign patents issued and pending.
*Discharge data includes loss through check valve, which is minimal.
