Pump Wiring Instructions
FOR YOUR PROTECTION, ALWAYS DISCONNECT THE PUMP FROM ITS POWER SOURCE BEFORE HANDLING.
All electrical connections must be wired and grounded in accordance with the National Electrical Code and all applicable
local codes and ordinances.
Risk of electrical shock,
Do not remove the power supply cord and strain relief or connect conduit directly to pump.
Installation and checking of electrical circuits and hardware should be performed by a qualified licensed electrician.
254 mm (10") MAX.
127 mm (5") MIN.
FIG. 2. Pump Control Switch Installation
Use the diagram above to secure the float switch properly and obtain the proper tether to customize the on-off cycle to each application. Note the
minimum off level shown above. On prepackaged systems, the tether length is set at 127 mm (5”).
Note:
Failure to keep within proper tether
limits may prevent reliable switch operation.
Note:
Cable must be mounted in horizontal
position.
Determining Pumping Range
(1" - 25 mm)
Use only as a guide. Due to weight of cable,
pumping range above horizontal is not
equal to pumping range below horizontal.
Ranges are based on testing in nonturbulent
conditions. Range may vary due to water
temperature and cord shape. As tether
length increases, so does the variance of
the pumping range.

General Information
PROGRESSING CAVITY
GRINDER PUMP DESCRIPTION
1. Pumps are constructed of class 30 cast iron protected with powder
coated epoxy for long life when pumping sewage in submersible
applications. The cutter assembly is comprised of stainless steel
components hardened to a value of 55-60 on the Rockwell C scale;
a star shaped cutter and a precision ground flat disk. Cutting action
takes place with the rotation of the star cutter against the stationary
cutter plate (see page 7).
2. The cutter mechanism on the model 810 & 815 is single directional.
3. Pump motors are single phase. Single phase motors require a run
capacitor, which is mounted in the upper cap of the pump. The units
have an internal thermal overload.
4. The 810 & 815 progressing cavity grinder pumps are single seal.
5. The pressure relief valve provides motor protection under inadvertent
shut-off head condition.
6. A progressing cavity grinder pump is an intermittent duty pump designed
for pumping sanitary sewage. It is not a dewatering or trash pump.
FIELD-ASSEMBLED INSTALLATION
1. Installation and piping instructions are included with the control panel,
rail system and basin instructions. If pump is being retrofitted to an
existing rail system, accessory parts may be required. Consult the
factory and advise make and model of rail system being used.
2. Refer to the appropriate Indoor/Outdoor prepackaged instructions
for more information on system installation.
3. All electrical connections including pump to control box and power
supply to control panels must comply with the applicable local codes.
Conduit and panel enclosure openings must have a gas-tight seal.
Installation of electrical panels and connections should be made by
a qualified licensed electrician.
4. A properly sized disconnect switch, supplied by others, shall be
installed on the service side of the pump and control panel.
