Viridian Systems Ltd


	VP Range of Pumps

	Viridian Systems Ltd. manufactures the very successful range of VP pneumatic borehole pumps in two basic sizes, namely the VP3 & VP4, for most landfill applications The VP 3 & 4 are intended for 3” & 4” wells respectively. The VP range is a cost effective, ATEX certified, reliable, automatic and long lasting solution to Leachate and condensate control problems within the landfill industry. VP pumps are fully automatic, self-regulating and require no external form of actuation. VP Pumps come with a 5-year Warranty on parts and labour excluding normal wear and tear.

The VP range has a pump to suit most requirements from the standard VP4 bottom entry to a top loading version, a narrow VP3 to the short pattern VP4 for those situations where you are trying to achieve as low a depth as possible. The pumping rates vary from well to well and the graph gives an indication of the performance.

Suitable for insertion into

Leachate Wells
Gas and Leachate Wells
Condensate Knock out pots

The flow rates generated by the VP range of pumps is governed by

Depth of well
Pipework design of both the Air main and Leachate Discharge main
Recharge rate of the well
Relative Air pressure
Height of liquid above the pump inlet

We have a modern well equipped workshop where we carry out maintenance, service and product developments. This facility houses our fabrication department where we manufacture Well heads for both Leachate and Gas wells, manifolds and Knock out pots. These are either to our own or customers designs.

We have installed and maintained Leachate pumps and systems for most of the major UK Landfill operators.
