Long-term Operation
The Dual Seal System gives long pump service life. The mechanical Dual Seal System
protects the motor from water with one shaft seal at the top and one shaft seal
below an oil chamber. The oil chamber provides lubrication for the seals and traps
any moisture that may leak through the lower seal. The upper seal operates entirely
in oil.
You Get Rugged, Safe Pumps
Now you can get certified explosion-proof pumps for applications such as sewage
wet wells where flammable gases exist. Class I, Division 1, Group C and/or D.
Reliable, safe operation is ensured because all castings are inspected for porosity
before, during and after machining. After assembly each explosion-proof pump is
thoroughly inspected to insure reliable performance.
Get Reliability and Efficiency
With Hydromatic explosion-proof pumps, you get the same reliability and high efficiency
designed into the non-explosion-proof pumps. Plus, you get added safety advantages
with F.M. approved, U.L. listed, explosion-proof Hydromatic pumps.
Hydromatic's explosion-proof non clog pumps features are:
FLAME-PROOF JOINTS
Flame-proof joints have 1 1/4" flame paths. These close tolerance joints
prevent any internal spark or fire from escaping into the environment.
MOTOR HOUSING
The explosion-proof housing wall is thicker throughout the case to give you extra
containment capability.
HEAVY DUTY BEARINGS
Hydromatic pumps provide you heavy duty bearings (minimum B-10 life of 50,000
hours) for long pump life.
2 MOISTURE SENSORS
Two moisture sensors in the oil chamber provide extra security.
The sensors are electrically isolated and made with stainless steel
connections and stainless steel probes.
LABYRINTH JOINT
The special labyrinth joint gives you added protection by preventing flame or
spark travel to the media being pumped.
