High head pumps for wastewater pumping
ABS is introducing a new series of HiLift pumps for high head pumping. The new range offers reliable wastewater pumping from buildings and sites.
The regulator incorporates two 100W heaters to prevent condensable dropout as the gas pressure reduces through the regulator.
The first heater preheats the media prior to the let down, and the second heater provides extra heat input after the gas temperature drops from the Joule-Thomson effect, thereby keeping the gas sample ultimately dry for accurate analysis.
The unique design has an extra advantage of allowing the heater sheaths to be removed and cleaned of carbon build up - inherent on hydrocarbon analysis, which eliminates the need to replace heater tubes or whole regulator assemblies.
