Horizontal reciprocating pump crankcase oil seal type?
Thread Content
The high-pressure flushing water pump of my unit is a three-piston horizontal reciprocating pump, model 3DS2-6/20. The motor and crankcase are driven by a V-belt. The crankshaft connecting rod oil seal was originally a polyurethane V-ring + oil separator ring, which caused serious oil leakage. Later, it was changed to a packing seal + oil separator ring, and there is still oil leakage. Dear friends, which type of oil seal is more effective in the application of this reciprocating pump?
Have you contacted the manufacturer? Maybe listen to their suggestions?
This pump is more than 20 years old and the original manufacturer of the equipment cannot be found;P
