Sometime in the spring of the mid-eighties in Baldwin Park, CA, MDM Pumps had a gentleman by the name of Frank Caswell come to the back door of the factory, begging the guys in the shop for a pump alternative that wouldn’t put his prize Japanese koi at risk. Frank was tired of oiled-filled bearings failing and poisoning his koi. Many times he found electrical shorts in the cord connection of the pump that would emit electrical current and shock the fish.
When the guys in the back told the executive staff of MDM there was a real marketing opportunity to help Frank solve his pump problems, as usual, Management took the time to understand the conditions of service and requirements before coming up with a solution that would meet Mr. Caswell’s needs. Here are those requirements:
The most important aspect of MDM’s pump sizing process for Frank was that it was targeted to properly size the pump at its best efficiency point, providing the least amount of shaft deflection, (due to unnecessary high pressure), in the motor and bearings. This promoted a significant increase to the pump service life not ever experienced by Frank with the submersibles he used before. Further, Frank was paying less in electrical costs every month due to the operational efficiency.
Frank was proud of the problem he solved for himself and quickly spread the word to other Koi keepers domestically and abroad.
Fast forward 36 years later and there is a massive install base and a brand name (Sequence®) that is uncompromised and undisputed internationally.
