Our DEPA® Pump and Spare Range Available to Order

April 16th 2020

We understand that many companies are currently struggling to source and secure delivery of Air Operated Diaphragm Pumps during the COVID-19 pandemic. As a sole distributor of DEPA® products in the UK, Tomlinson Hall has large volumes of stock available directly off the shelf and ready for next day delivery.

We have experienced a surge in demand in our DEPA® range – recognised as one of the world’s leading brands of superior quality, positive displacement pumps – and we are able to continually replenish our stock, as and when required.

To showcase the full range that we have on offer, we have put together two videos showing both our DEPA® pump range and the genuine DEPA® pump spares available.


In stock, our DEPA® Air Operated Pumps – fully ATEX certified and fitted with closed surface diaphragms – are available in all sizes including ½”,1”, 1 ½”, 2” and 3”. With flexible multi-port connections, the pumps are available in cast aluminium PTFE, polyprop, polished and cast 316 stainless steel.

The latest addition to the range is the new DEPA® Closed Surface Diaphragms Series nopped E4®, which really sets a new precedence of how all pumps will be made in the future and offers the following benefits:

Extended lifetime

The absence of the outer piston reduces wear around the flexing area, increasing diaphragm life.

Eliminates leaks

Integrated insert eliminates a potential leak path within the pump. The pre-defined fixing feature of the outer rim design improves safety for both the customer and environment.

Ease of maintenance

Pump maintenance is simplified and requires only hand tightening of the diaphragm. Modular design ensures all diaphragms are interchangeable with all DEPA® pumps.

Easy to clean

Clean surface reduces the build-up of impurities, improves flow and increases energy savings.

We also have the following available off the shelf:  

  • Diaphragms in all sizes and materials
  • Valve balls, valve seats and 0-rings available in all five sizes
  • Full overhaul spares kits
  • Air control valves, internal and external
  • Suction and delivery manifolds plus air and liquid housings
  • Full range of gaskets and sealing rings available in all sizes.

Now, more than ever, it is so important that all companies pull together and Tomlinson Hall will continue to provide any support it can to keep essential industries pumping.

If you have any enquiries at all, please call the office directly on +44 (0)1642 379500.
