Separ UK History

Separ UK are suppliers of fuel filtration equipment and fuel polishing systems to the generator, heavy machinery, transport, agricultural and marine industriesSWK2000-18U


Separ Distribution UK was formed in the early part of 1989 and commenced trading on 1st July that year with only one product range, Separ Fuel Filters (Willibrord Losing Filter-Technik of Hattingen). The Separ Filter/Water Separator range covers diesel and petrol engine applications, with our early customers being in the UK marine market.
Our main market is marine (pleasure, coastal commercial and fishing) with 16 distributors being appointed in the first 18 months of trading.
In 1993 to further develop the business the company started to look for new products that complemented the Separ range.
Having already picked up the fuel conditioning devices to control bacterial growth in middle distillate fuel, in 1994 Separ distribution UK became a distributor for Mahle filtration equipment (lube oil) through their main distributor in the UK, servicing the marine and generating set builders. By this time the company was also selling Separ equipment into the off-road and plant markets.
1995 was launched, allowing customers 24/7 access to technical data, as well as selection data and specifications for our product ranges.
Separ UK's own brand name "WASP" was registered and trademarked. Products made by or for Separ UK other than those already carrying the Separ name will therefore be WASP branded.
In 1998 we were appointed as sub-agents for CJC lube and fuel oil filtration equipment, together with Reverso Oil change systems from Reverso in Florida.
To improve our technical capabilities and assist with ISO 9001 (which we attained initially in September 1998 and have maintained ever since), we developed our technical and quality department. This division is core to our belief in quality above all else.
The WASP range of fuel strainers is launched
In 2005 Separ took on a new product range, the Fuel Polishing System. This is a turnkey solution to the growing problem of poor quality fuel, fuel degradation, long storage fuel quality and the fuel bug. It is conceived for both the boat industry and building protection (backup generators etc).
A new version of the web site was launched
With continued growth, Separ UK moved from its original Watford facility to a new, larger custom-built location in near-by Kings Langley in April 2007.
As most of our customers and supplied already referred to us as simple Separ UK, the company name was officially changed from Separ Distribution UK to Separ UK. 
2010 Separ UK celebrated its 21st Anniversary (click here for more)
2011 WASP PFS Ltd was created to deal with WASP branded products / fuel polishing system sales. was launched specifically to handle all non-separ related enquiries. A revised and updated website launched 
2012 Rapid growth in WASP PFS Ltd sales following the introduciton of biofuels  
2013 WB and W-PFS range launched
2014 On line sales launched for WASP PFS Ltd
2015 WASP PFS Ltd spares centre launched. WASP now selling its own brand products into over 30 countries worldwide






The business has grown significantly since its early days, but has ensured that it's key principles of honesty, professionalism and quality in all areas have been maintained - meaning customers who start with Separ, stay with Separ.
