Installation
This pump may be installed on a guiderail lift-out system for ease of inspection
and service. Guide-rails allow removal
of the pump without disturbing the
piping and eliminates the need to enter
the basin. If installed with a guide-rail
system, place the pump opposite the
influent opening to prevent stagnant
areas where solids can settle.
Install the pump on a hard, level surface.
Never place the pump directly on earth,
clay or gravel surfaces. The basin must be
at least 18” in diameter and 30” deep.
The discharge pipe must not be smaller
than the pump discharge.
The motor is provided with a thermal
overload switch (Single Phase Pump
Motors Only). If the motor overloads
or overheats for any reason, the switch
opens, stopping the motor. As soon as the
motor cools to normal temperature, the
switch automatically closes and restarts the
motor. On 3-Phase pumps, the installer
must provide the Motor Protection. In
accordance with the National Electric
Code, all 3-phase pumps must be
installed with magnetic starters having
3 leg overload protection. For duplex
installations, both pump motors must
have separate overload protection.
Hazardous voltage.

Operating Instructions
The double seal grinder pumps contain
an electrode for detecting water within
the unit. The electrode is housed within
the seal chamber, isolated from the
motor chamber by a mechanical shaft
seal. If the electrode detects water
within the oil-filled housing, it will close
the circuit to the alarm light in the
control panel, indicating the motor must
be serviced before the upper mechanical
shaft seal fails. The BLUE conductor is
connected to the seal leak probe.
Refer to Wiring Diagrams for model
specific wiring directions (See Figure 2).
Control Panel and
Level Sensing
BAGP1 & BADSGP1 grinder pumps
have internal start and run capacitors.
No control panel is required for
operating the pump. An alarm box is
recommended for high water alarm.
See Chart 2 for starting component
specifications per model.
BARDSGP1 and BAHGP2 models require
control boxes containing properly sized
start and run capacitors. Single-phase
models require a Single-Phase Control
Box with starting components equal to
specifications listed in Chart 2.
The three-phase models require a ThreePhase Control Box with circuit breaker
and overload heaters per the chart.
Intrinsically safe type float controls are
recommended for all applications. An
intrinsically safe control panel relay will
limit the current and voltage to the level
controls. A control panel can be supplied
with this type of circuitry.
Recommended level sensing settings:
1. The lower “turn-off” control should
be set so the pump stops with the
liquid level at the top of the motor
housing.
2. The upper “turn-on” control should
be set approximately 8” above the
“turn-off” control. This should limit
the number of pump starts to not
exceed 10 starts per hour.
3. The “lag-on” control for duplex
operation should be set 4” above
the “turn-on” control.
4. The “alarm” control is set 10” above
the “turn-on” control.
5. No control should be set above the
inlet pipe.

Maintenance
Only qualified mechanics with proper
tools and knowledge should attempt to
service this pump.
REPLACING GRINDER IMPELLER AND
SHREDDING RING
Note: This is the only disassembly
operation permitted in the field. All
other repairs must be performed at an
authorized service center or the factory.
Standard Tools Required:
• Standardsocketwrenchset
• Standardsetofopen-end
wrenches
• Hammer
• Visegrippliers
• Allenheadsocketset
• Screwdrivers
• Wirebrush
Disconnect all power
and control wires to
motor at the control panel before starting
the disassembly operations. Do not rely
upon opening the circuit breaker only.
Hazardous cutter.
Rotation of the cutter
with hands in the cutter area can cause
loss of fingers. Keep hands away from
the pump inlet opening when working
on or handling the pump for any reason.
Pump should be
sanitized with bleach
before starting work.
• Pumpshouldbethoroughly
cleaned of trash and deposits
before starting disassembly
operations.
• Wearprotectiveglovesand
clothing.
• Alwaysusearagontheimpeller
when turning to prevent cutting
hands on the sharp edges of the
shredding ring.
DISASSEMBLY OF SHREDDING RING
AND GRINDER IMPELLER
1. Remove 3 bolts from grinder ring
flange with socket wrench. The
grinder ring is pressed into the
flange for convenient removal.
2. Thread 2 of the bolts (removed from
the grinder ring flange) into the
tapped back-off holes in the flange
and evenly tighten the bolts to back
the grinding ring out of the pump
housing.
3. Hold the grinder impeller by prying
against the impeller cutting bar and
remove the cap screw from the end
of the shaft.
4. Use a large screwdriver to the slot
of the shaft and tap on the cutter
vane with a hammer. Tap in a
counterclockwise direction (thread is
right-hand).
5. If the impeller removes easily, clean
and replace if worn.
6. Make sure the pump impeller has
not loosened when the grinder
impeller was removed. This can be
checked on reassembly of grinder
impeller and shredding ring. The
tips of the impeller cutter vanes
should extend 1/8” below the
bottom of the shredding ring. If
the distance is greater, the pump
impeller has loosened. If the
distance is less, shredding ring is not
properly seated.
7. After the volute case has been
removed, wrap emery cloth around
the shaft and hold with vise grip
pliers. Us a cloth on the impeller and
thread tight against shoulder on
shaft.
8. Clean all threads with a wire
brush and file smooth any nicked
threads. Apply an anti-seize or other
graphite compound on threads
before replacing grinder impeller.
9. Make sure cap screw in bottom of
pump shaft is tight. Hold impeller
with screwdriver between the cutter
bar and teeth of shredding ring
while tightening the cap screw.
10. Make sure the impeller turns freely
by hand after reassembly. Some
drag will be present due to the
shaft seals. There should not be any
binding or tight spots when turning
the grinder impeller.
11. If there is any rub or drag on the
shredding ring, loosen the 3 bolts
in the shredding ring plate and
tap lightly with the hammer to
loosen. Retighten the bolts. Be
sure to tighten the bolts evenly,
applying pressure on all 3 bolts. DO
NOT COMPLETELY TIGHTEN ONE
BOLT BEFORE TIGHTENING THE
OTHER BOLTS. THIS WILL CAUSE
MISALIGNMENT AND LOCKING OF
SHREDDING RING AND GRINDER
IMPELLER.
