The rental business has offered us a great testing ground for different applications, different types of products to be pumped and different levels of use and abuse.  This has allowed us to make modifications and adjustments to our product line, to improve our products as new and unexpected problems occur.  We here at John E. McCausland, Inc. are confident that we build high quality, easy to service and durable equipment with some of the best features in the industry.  The following information describes some of the features of our system that meet or exceed the industry standards for these types of pumping systems.

Our power units are powered by John Deere diesel engines.  They have a heavy duty frame welded construction with lifting bale.  They come equipped with a Murphy shut down system, which includes an engine oil pressure switch, engine coolant temperature switch, hydraulic oil temperature switch, and hydraulic oil level switch.  These switches will shut down the system before any severe damage occurs.  The hydraulic system has a heat exchanger to remove heat from the oil, and is filtered to 10 microns.  Our power units are also equipped with hydraulic oil and fuel tanks that have baffles, sumps with gravity drains and removable covers for cleaning.

Our submersible pump heads are constructed with durability and performance in mind.  Our pumps are all designed with an easy to remove top motor plate to access the impeller and interior of the casing.  Allowing for easy inspection and removal of any obstructions.  Our pump impellers are dynamically balanced for optimum performance and the larger pumps with heavier impellers have large bearing carries to support the load.

These bearing carries and motors are both protected by an external lip seal and an internal mechanical seal assembly.  The lip seal acts to protect against product in the pump casing entering the hydraulic system.  And the mechanical seal assembly seals the hydraulic system from hydraulic oil leakage.  These mechanical seal assemblies are of the single spring type with hard faces which can be lapped to resurface the sealing faces making them last virtually forever.  This mechanical arrangement is sealed around the motor shaft by a rubber bellows.  This bellows and the external lip seal are the two points of least resistance and are easy to replace with a minimal cost compared to other seal arrangements

The mechanical seals and bearings in our bearing carriers and motors are self lubricated by the hydraulic oil flowing through the system.  The bearing and seal housings are flooded with oil from the hydraulic system and are ported for pressure relief.  This case drain is the third hose in the hydraulic assembly.

Our hydraulic hose assembly is made up of top quality hose rated above the recommended operating pressure for added safety.  There is a main pressure hose, main return hose and case drain.  These 3 hoses are different sizes with male to female connectors to eliminate any possibilities of incorrect setup.  Hoses are in standard lengths of 50 feet and are assembled with leak proof, quick disconnect hydraulic fittings.
