The X41 Series line of seal-less regenerative turbine pumps (also known as canned, hermetic, or zero emission pumps) is designed to handle applications with difficult to seal fluids where absolutely leak free performance is required, and mechanical seals simply cannot provide the needed reliability, protection, and performance. All of this is accomplished at a price point previously unseen in the industry, and is often comparable with other mechanically sealed solutions, but without the leaks and inevitable seal maintenance. Water/glycol mixtures and exotic heat transfer fluids present no difficulty for these units at fluid temperatures from -84°C up to 150°C. The canned motor design is far preferable to magnetic drive couplings as it does not add excessive length to the unit in tight OEM enclosures, or suffer from the magnetic de-coupling problems often associated with mag-drive solutions. Three bearings, high strength cast stainless steel components, and a seal-less design assure extended maintenance free life. To demonstrate the potential reliability of these units, well over 800 X41's have been shipped into the field from 1997 thru 2003 into water/glycol chiller applications. Of these 800+ units at end user sites, none have yet been reported to the factory as failed, leaking, or requiring any repair. For other special fluids and applications, optional elastomers, electrical connections, and variable frequency drive control packages are all available to custom fit your particular needs.

Variable Speed Option

Most MTH pump products are available with an optional variable frequency controller and a pressure transducer in a completely assembled and tested unit. A closed loop pressure transducer / variable frequency drive combination can eliminate the need for costly pressure relief valves and their associated plumbing problems, while gaining the ability to maintain constant discharge pressure by automatically varying pump motor speed. Signal inputs and outputs are available on the drive for accommodating a variety of external controls, alarm set point signals, and other programmed outputs.

This package is particularly helpful to OEM manufacturers whose equipment is exported to countries utilizing 50-Hertz electrical supply systems. The drive can take inputs at 50 or 60Hz at a number of different voltages, and produce a variable frequency and voltage output suitable for pump output requirements, without any rewiring or user intervention required. This is a significant step forward in the design of a truly power source independent, worldwide product. Variable frequency controller / transducer packages are also available for customer applications where flow, temperature, or other variables need to be maintained. Please consult the factory for further information on these options.
