ASPEN (England)

In 1992 three engineers developed a range of reliable peristaltic pumps to satisfy the demands of the air conditioning industry, as the existing condensate removal methods did not meet the needs of installers. From these humble beginnings Aspen Pumps now boasts an impressive range of Mini, Tank, Peristaltic, Supermarket and Boiler pumps as well as a full range of installation accessories.

The achievements,the awards and success of Aspen Pumps has been built by the hands-on experience of installation engineers and has grown into the market leader in condensate removal.

Aspen Pumps:

There are many benefits to using a condensate removal pump over gravity, but what specific technologies are available, and what are their advantages?

There are four different types of condensate removal pumps:

• Piston:Piston technology uses a small oscillating piston that oscillates at 60 cycles per second. It uses positive displacement and can operate between two one-way values.

  Piston pumps are quiet, small and have flexible installation options. Because the piston pumps are very quiet (if designed right) they suit indoor use near meeting rooms or in offices. For Aspen’s quietest pumps please see our mini pump range and silent+ mini pump range. Aspen has solved the potential problem of siphoning with their revolutionary Anti Siphoning Device and now include this free with all Mini Pumps and Silent+ Mini Pumps.

• Peristaltic:Extremely reliable and being able to pump potentially unclean water, they pump long distances and can be installed a great distance away from the unit meaning this is ideal for hotels or buildings where the units are located remotely or in inaccessible rooms. With their long life they are truly a long-term investment. Aspen pioneered the use of the peristaltic pump 20 years ago

• Centrifugal:Centrifugal technology is a rotodynamic pump that uses a shade pole motor connected to rotating blade that’s spinning within an enclosed housing to create flow.

  These pumps may be noisy but are cost-effective and ideal for applications that require higher water volumes, for example the tank pump range. The centrifugal pumps must be placed underneath the unit.

• Diaphragm: Another type of positive displacement pump. These pumps have been developed for specialist applications, such as the Aspen supermarket range.
