Pump
Information
Pump Models:
These instructions cover the
installation and service of the
Hydromatic SPX50 and SPX50H
series submersible sump pumps.
The models are CSA listed
explosion-proof for hazardous
wastewater locations Group 1,
Div. 1, Class D.
Motor HP & Voltages:
The SPX50/SPX50H sump
pumps are offered in single phase.
Voltages will vary according to
the application and can be seen in
the tables in this manual.
Electrical Controls:
All of these pump models must be
used with a control panel.
Hydromatic built control panels
are designed to supply the correct
electrical controls and motor
starting equipment and include
the circuitry for moisture and heat
sensors. It is recommended that a
Hydromatic built control panel be
used so that all warranties apply.
General Construction:
The SPX50/SPX50H motor
construction is designed to
meet CSA
requirements for
Group 1, Div. 1, Class D
wastewater applications. These
models are certified and
nameplated with this approval. A
cross-sectional view of the
internal workings of the pumps
can be seen on pages 12 & 13.
The motor chamber and seal
chamber are filled with a high
dielectric type oil for improved
lubrication and heat transfer of
the bearings and motor. Since the
bearings have been designed for
50,000 hours of life, the oil
should never require replacement
under normal operating
conditions. An air space above
the oil level in both the seal and
motor chambers is provided to
allow for the expansion of the oil
when at operating temperature.
The power and control lines are
sealed and strain relieved on the
outside entrance with a standard
cord grip, and internally through
the use of a dielectric potting
resin surrounding the electrical
wires.
Internal connection wiring
diagrams are shown in page 6.
All of the pump fasteners and
shafts are made from
corrosion-resistant stainless steel,
while the pump castings are made
of ASTM A-48 Class 30 cast iron,
and the multivane vortex
impellers are made from Class 20
cast iron.
General Installation:
Various configurations and
methods of plumbing this series
of sump pumps may be used.
NOTE: If the SPX50 and
SPX50H explosion-proof pumps
are used in conjunction with a
rail lift-out system, it must be
a UL
or CSA approved
nonsparking, explosion-proof
system.
IMPORTANT: If the following
guidelines are not followed, the
UL explosion-proof approval is
void.
Explosion-Proof Service:
These pumps are to be used
for handling contaminated septic
tank effluent, sewage, and storm
water only. The SPX50/SPX50H is
CSA approved (Group 1, Division
1, Class D) to handle a wide
variety of pollutants, including
gas and oil. Do not use in other
hazardous locations. These
motors must be repaired
and serviced only at a Hydromatic
authorized service center or at
the Hydromatic factory. Any
unauthorized field repair voids
warranty and the explosion-proof
rating.
CAUTION: After the pump is
installed and wastewater has
entered the basin, there is
danger. Sewage water gives
off methane and hydrogen
sulfide gases, which are
poisonous. Never enter a wet
well unless the cover is open for
a sufficient period of time to
allow fresh air into the basin. It
is recommended that a man in
the basin have a harness on
with a rope to the surface, so
that he can be pulled out in
case of asphyxiation. It is for
this reason that Hydromatic
recommends using the rail
lift-out system so that no
service is required inside
the basin.
