The MUD PUPPY 250 pump generation is an improved version of older 214 inch shaft pumps. The MUD PUPPY 250 pump is designed to give longer service life through a wear pad replacement casing, superior bearings, stainless shaft sleeve, labyrinth bearing cap seals, semi open impellers and stainless casing nuts.
There are many principles of proper pump installation and applications as well as special considerations for the MUD PUPPY 250 design that, if followed, will further enhance its performance.
This document will deal with both general and specific recommendations for improved Mud Puppy 250 performance in both oilfield and also industrial applications.
- Operate the pump only in the performance range for which it was designed.
- The pump driver must drive the pump CLOCKWISE when viewed from the coupling end. Reversing the rotation will damage the pump.
- Do not operate the pump with the suction or discharge valves closed.
- Adjust the packing so that a small amount of leakage remains for lubrication and cooling (not applicable for pumps equipped with mechanical seal).
- When operating in drilling mud, prevent packing drip page from clogging the drip area and hardening around the slinger and front seal. See Section E for mechanical seal installation.
