OSP33 SUBMERSIBLE SUMP/EFFLUENT PUMP
The Hydromatic OSP33 sub-
mersible pump is specifically
designed to meet the demands
of residential sump, elevator pit,
septic tank effluent, industrial
circulator and transfer tank
applications.
The 1-1/2 inch NPT dis-
charge pump is available with a
powerful 1/3 horsepower
motor, in both automatic and
manual configurations; and can
handle capacities up to 60 gal-
Ions per minute and heads to 25
feet.
The OSP33 features a heavy-
duty cast iron construction that
provides durability in rugged
applications, as well as assisting
in dissipating heat from the
motor, for cooler operation,
The pump's non-dogging bronze
impeller, which is threaded to a
stainless steel shaft provides long
life even in demanding applica-
tions; and is capable of handling
up to 5/8 inch spherical solids
and lint.
The OSP33's oH-filled motor
provides superior cooling
characteristics, allowing the
motor to run cool and quiet for
years. This oH-filled design also
provides permanent lubrication
of the shaft bearings, mini-
mizing maintenance and
extending the service life
of the pump. In addition, to
protect against overheating, tlg. e
motor windings contain an auto-
matic reset thermal overload.
Automatic models feature the
exclusive Hydromatic diaphragm
pressure switch, which provides
proven reliability in installations
where a float might hang up.
It also incorporates a unique
piggyback plug arrangement,
which allows for simple con-
version to manual operation by
simply removing the switch plug
and in~-~Ing the motor plug
directly into the electrical outlet.
This feature provides an easy
way of periodically cycling the
pump to ensure it is operating'

OSP33 TYPICAL INSTALLATION
Diaphragm Pressure
Switch
For automatic operation the
OSP33 uses the exclusive Hydro-
matic piggyback diaphragm
pressure switch. The switch,
which is mounted to the pump
with a snlnless steel mounting
strap, is sealed in a tough, non-
corrosive, engineered, thermo-
plastic housing to provide years
of service~
The diaphragm pressure switch is
perfect for applications involving
Small diameter sumps where a float
switch might hang up.
Piggyback Switch Plug
The Hydromatic wide-angle float
switch features a unique piggyback
plug arrangement. The pump power
cord plugs into the back of the
switch plug to provide automatic
operation. To operate the pump
manua!!y~ simply plug the pump
power cord directly into the electri-
cal outlet, bypassing the switch plug.
The pigback plug provides ease of
service and allows the pump to be
cycled manually on a periodic basis
to ensure proper operation.
