Available in a range of sizes and variations, and capable of discharging up to 1.1 litres of liquid per cycle. The bottom-filling versions are specifically designed for the harsh conditions of pumping landfill leachate.
Available as a top loading version, for groundwater remediation applications, as well as a short version, and the ‘LDD’ (low drawdown) when minimum liquid head is vital. The VP2 and VP3 range has a reduced discharge capacity but it is ideal for smaller borehole sizes.
As the VP pumps are driven by compressed air, a multi-well system would have an air-main connecting each pump – a far safer power source than electricity cables and less costly. VP Pumps also do not require an external form of control.
Pulse Counters, for volume and flow rate measurement also available.

VP Pumps Range
Unrivalled Engineering:
The materials of construction have been selected for the harsh environment in which they are working, such as aggressive media, high-temperature and suspended solids. For these reasons materials of construction include:
•316L Stainless Steel •17/4 Stainless Steel
•PEEK •PTFE (Teflon®) •UHMW PE
•FPM (Viton®) •PVDF (Kynar®)
•Syntactic •GRP
Corrosion & Temperature Resistance:
Exceptional corrosion & temperature resistance due to the highest quality
materials of construction which includes:
-
- 316L Stainless Steel for all major metal parts & fasteners
- 17/4 Stainless Steel for magnetic parts
- PEEK rocker assembly
- PTFE (Teflon®) discharge check valve ball
- UHMW PE actuator rod & inlet check valve shuttle
- FKM (Viton®) for all ‘o’-ring seals
- PVDF (Kynar®) for minor plastic parts
- Syntactic high performance float, collapse rating 4000 psi @ 175°F, max. operating temp. 250°F
- FRP high performance filament wound epoxy composite casing, max operating temp. 250°F, tested to 800 psi @ 175°F
- 316L Stainless Steel casing available on request
Better by Design:
-
- Solid, machined pump head with integral discharge check valve
- No penetrations through the centre discharge tube meaning no air leakage into discharge
- Solid machined bottom check valve assembly with minimal parts, exceptional rigidity and easy disassembly
- Solid domed bottom end to aid installation and deflect gas
- Rocker arms are not prone to stress-cracking
- Air inlet and exhaust valves secured with cotter-pins
- Discharge check valve ball easy to replace
- Pressure tested to 800 psi @ 175°F
- Compatible with I-Fit couplings or standard hose-barbs
- Exceptionally rugged construction
- ATEX Zone 1 certified
