Submersible Effluent Pump
• Continuous Duty Rated
• Septic Tank Effluent
• Flood Control Units
• Industrial Circulators
• Elevator Pits
• Basement Sumps
OSP50
The Hydromatic OSP50 submersible 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 discharge pump is available with a powerful 1/2 horsepower motor, in both
automatic and manual configurations, and can handle capacities up to 60 gallons per minute and
heads to 25 feet.
The OSP50 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 nonclogging bronze impeller, which is threaded to a stainless steel shaft, provides long life
even in demanding applications, and is capable of handling up to 5/8 inch spherical solids and lint.
The OSP50’s oil-filled motor provides superior cooling characteristics, allowing the motor to run
cool and quiet for years. This oil-filled design also provides permanent lubrication of the shaft
bearings, minimizing maintenance and extending the service life of the pump. In addition, to protect
against overheating, the motor windings contain an automatic 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
conversion to manual operation by simply removing the
switch plug and inserting the motor plug directly into the
electrical outlet. This feature provides an easy way
of periodically cycling the pump to ensure it is
operating properly.
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
manually, simply plug the pump power cord directly
into the electrical outlet, bypassing the switch plug.
The piggyback plug provides ease of service and
allows the pump to be cycled manually on a
periodic basis to ensure proper operation.

OSP50 - Submersible Effluent Pump
A. Water-resistant power cord with molded plug is
available in 10 or 20 foot lengths, and is easily
field serviceable.
B. Upper and lower ball bearings support motor
shaft, minimizing the effects of impeller thrust
loads. This design results in minimum friction and
perfect alignment of rotor, for longer service
from pump.
C. Oil-filled motor provides superior cooling and
permanent lubrication of bearings, minimizing
maintenance and extending service life.
D. Powerful 1/2 HP motor runs cool and quiet for
long life. Motor windings contain automatic-reset,
thermal overload protection.
E. Mechanical shaft seal is carbon- and ceramic-faced
for long, leakproof life.
F. Heavy-duty, cast iron construction provides long
life in rugged applications.
G. Discharge is 1-1/2 inch NPT.
H. The nonclogging bronze impeller, which is thread-
ed to a stainless steel shaft, provides long life in
corrosive applications, and is capable of
handling up to 5/8 inch spherical solids and lint.
I. Bottom-suction design alleviates buildup of
debris, providing optimum pump performance and
reduced maintenance.
J. Multiple strainer inlets prevent foreign objects
from clogging pump, providing optimum operation
and reduced maintenance.
