Price List - Pump Servicing
Island Scientific can fully strip and overhaul most makes and types of Vacuum Pump.  This includes decontamination of Pumps from both the semiconductor and chemical industry applications.

Our Pump service price guide is based on the following work being undertaken.
Full Service

  • If major repairs are needed a quotation will be sent for approval before the service is completed.
  • The pump motor stripped, cleaned and fitted with new bearings.
  • Pump and motor re-assembled with new 'O' rings, seals,bushes and bearings. 
  • Pump run and fully tested before re-packing and despatch back to customer.


If the pump has been used on a semiconductor or chemical application the cost of decontamination starts from £75.00/pump depending on the model.

If down time is your major concern we may be able to offer a service exchange unit from our extensive range of reconditioned units.

Above prices exclude delivery, collection and VAT.

Prices do not include decontamination please add for decontamination £90 (approx. dependant on Pump model).

Pump only decontamination with no re-build from £150.00.

We will fax you for any extra work that may be required such as new rotors and stators. If we find the pump is beyond repair we may be able to supply a service exchange unit from our existing stocks of reconditioned equipment.
