MP PUMPS HTO SERIES

OPERATION AND MAINTENANCE

Thermal oil vapors leaking from a system can be

highly flammable.

Any system leak should be repaired immediately.

Do not insulate the pump or system piping with

porous flammable insulation. Fluid may wick,

decompose and spontaneously ignite.

Ideal mechanical seal life is 20,000 hours.

Reduced seal life may be experienced from

extreme conditions.

Recommended spare parts and service parts to

rebuild the HTO-120 are:

At disassembly, check the impeller and other

wear items for unusual wear. Replace if

necessary.

When servicing the pump, care should be taken

that the pump has cooled to a sufficient

temperature to permit disassembly. The

product should be drained from the pump

housing and disposed in accordance with the

fluid manufacturer's recommendations.

Operating personnel should be warned to

exercise care and utilize eye and skin protection

when servicing the pump.
