New EF Series rechargeable motor available

As well as single phase electric and air motors, a rechargeable motor option has recently been introduced for the EF Series for sites where an electric or air supply to power a pump is not available.  The S6 12-Volt Lithium Ion Cordless Rechargeable Drum Pump Motor fits all EF pump tubes and is versatile, economical and extremely portable.

The S6 motor cordless design makes it easy to transfer fluids virtually anywhere, with maximum fade-free performance, equivalent to a corded AC powered motor.  The latest Lithium ion batteries have a much higher energy density compared to nickel cadmium (NiCd) or nickel metal hydride (NiMH) batteries so the pumps can operate effectively for up to 50 minutes between charges.  Also, Lithium ion batteries have no 'memory' effect which means they can be recharged at any state of their discharge.

The unit has a solid-state electronic control circuit that monitors all aspects of the motor and battery pack to ensure reliable operation and long-life, while dual cooling fans help to improve the performance and life of the battery pack.  Multiple charging options include 115 or 230 volt AC and for mobile applications an automobile or commercial vehicle port option will suffice.  The motor housing has an integral wall-mount hanging bracket so it can be stored internally and not be misplaced.

The rechargeable motor can be used with any of the Finish Thompson EF Series tube sets, polypropylene, pure polypropylene/PVDF and stainless steel while the 2-speed motor ensures smooth and precise dispensing.  On the low speed setting, the pump / motor will run for approximately 50 minutes between charges and the high speed setting, it will run for around 20 minutes.

The S6 Rechargeable Drum Pump Motor will be an ideal option for transferring fluids from drums, barrels and carboys where a power supply is not available, is too distant from the point of pumping, or where fluids need transferring in remote, isolated locations.
