Product Description
MYERS MSP50 SUBMERSIBLE SEWAGE EJECTOR PUMP
Applications
• Continuous Duty Rated
• Residential Sewage
• High-Capacity Sump
• Septic Tank Effluent
The Myers MSP50 submersible pump is specifically
designed to meet the demands of handling wastewater
and sewage in residential and commercial building
applications. The 2 inch NPT discharge pump (3 inch
discharge optional) is available with a powerful 1/2
horsepower motor, in both automatic and manual
configurations; and can handle capacities up to 150
gallons per minute and heads to 29 feet.
The MSP50 features a heavy-duty cast iron
construction that provides durability in rugged
applications, as well as assists in dissipating heat from
the motor, for cooler operation. It is also available
in an all bronze model. The pump’s non-clog, noncorrosive, cast iron impeller, which is threaded to a
nickel plated steel shaft, provides long life even in
demanding applications; and is capable of handling
spherical solids up to 1-1/2 inches and lint. The MSP50
also features precision, carbon and ceramic-faced
mechanical shaft seals that are extensively lapped,
providing for a long, leakproof life.
The MSP50’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 (1 Ø).
Water level is controlled on automatic models by
Myers’s proven diaphragm type pressure switch,
which is sealed in a water tight thermoplastic housing.
Double diaphragm construction provides added
protection by preventing liquid or foreign matter from
entering switch.
A Water-resistant power cord with molded plug is available in
10 or 20 foot lengths, and is easily field serviceable.
B Oil-filled motor provides superior cooling and permanent
lubrication of bearings minimizing maintenance and extending
service life.
C Powerful 1/2 HP motor provides cool and quiet operation.
Motor windings contain automatic thermal overload protection.
D The high-capacity, non-clog, cast iron impeller, which is
threaded to a nickel plated steel shaft, efficiently handles up to
1-1/2 inch spherical solids. Pump-out vanes on back of impeller
prevent stringy materials from binding impeller or shaft.
E Upper radial and lower thrust bearings are heavy-duty, singlerow ball bearings that are permanently lubricated for servicefree life.
F Heavy-duty, cast iron construction provides long life and assists
in heat dissipation for cooler motor operation. All-bronze
model, SP50AB, is also available.
G Precision, mechanical shaft seal is extensively-lapped, carbonand ceramic-faced for a long leakproof life.
H Bottom inlet has no screen to become clogged, providing
optimum pump performance and minimal maintenance.
I Discharge is a standard 2 inch NPT (3 inch is optional).
