Unpacking Pump:

Remove pump from carton. When
unpacking unit, check for
concealed damage. Claims for
damage must be made at the
receiving end through the delivery
carrier. Damage cannot be
processed from the factory.

WARNING: Before handling
these pumps and controls,
always disconnect the power
first. Do not smoke or use 
sparkable electrical devices or
flames in a septic (gaseous) or
possible septic sump.

Pump Description:

The Hydromatic pumps covered
by these instructions are
submersible grinder pumps.

The cutter blades are on the 
suction side of the centrifugal
pump impeller and discharge
directly into the inlet of the
impeller. The integral stainless
steel pump-motor shaft is sealed
by two mechanical seals with 
an oil chamber between the seals
to provide lubrication for both
seal faces.

A radial sleeve bearing, lubricated
by the oil in the seal chamber, is
located between the seals and
takes the radial load from the
pump impeller and cutter blades.

The motor winding, rotor, and ball
thrust bearing are mounted in a
housing sealed and filled with oil
to lubricate the bearing and 
transmit the heat from motor
winding to outer shell. The ball
thrust bearing is held in a movable
cap so that the axial cutter and
cutter ring clearance can be
adjusted from the outside without
the use of shims.

The power cord is sealed into the
motor housing with a cord grip,
and the individual conductors are
sealed into the cord cap with
epoxy sealing compound.

Application:

These pumps are designed for
either home or industrial sewage
discharge applications with a pH
ranging from 6 to 9, specific 
gravities from 0.9 to 1.1, 
viscosities ranging from 28 to 35
S.S.U., and temperatures up 
to 140°F.

Information

Codes:

All local wiring codes must be
observed. Consult the local
inspector before installation to
avoid costly delays that can 
occur due to rejection after job 
is finished.

Installation
Instructions

Location:

If pumps are installed in an 
existing basin or concrete sump,
the piping can either be connected
permanently or rails and brackets
can be furnished for mounting to
walls of basin. In either case, be
sure that the Hydromatic non-clog
check valve is used and that the
pumps are submerged in a vertical
position. The complete factory
built packaged system is 
recommended for the most 
satisfactory installation and 
generally for the lowest cost
where expensive installation labor
is involved.

Electrical Connections:

Make all connections from motor
to control panel to comply with
local codes.

CAUTION: Be sure ground
wire is connected to a good
ground such as a water pipe.
This is important for safety.
