Product Description
Myers MESPD50/100H Cast Iron Effluent Pumps
The MESPD50/100H are completely submersible, “high-head”, dual-seal pumps for use in septic tank effluent applications.
Two (2) carbon/ceramic type 21 mechanical seals mounted in tandem
Oil-filled motor with automatic resent thermal overload for maximum protection (single phase models)
Capacitor start for increased starting torque (single phase models)
The Myers MESPD50 Submersible Effluent Pumps handles flow capacities up to 110 gallons per minute and heads
to 50 feet, while the MESPD100 handles capacities up to 140 gallons per minute and heads to 63 feet. Additionally,
the MESPD50’s oil-filled motor allows for superior cooling characteristics and provides permanent lubrication of the
shaft bearings, minimizing maintenance and extending the service life of the pump.
Automatic models (1/2 HP) feature the exclusive Myers 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.
FEATURES:
High-quality cast iron pump volute, motor housing,
and seal housing construction that help to ensure a long
service life.
Non-clogging, two vane, cast iron impeller threaded to a
stainless steel shaft provides long life in
demanding applications.
A seal-failure sensor probe (for connection to a seal
failure alarm) is standard on three-phase units and
available as an option on single-phase models.
Two carbon- and ceramic-faced mechanical shaft seals
are mounted in tandem to provide double protection
against water entry for a long, leak proof life.
