Series E^Plus Dosage Pumps

The Series E^Plus range is identical to the Series E range in terms of physical size, weight, number of models, output and pressure ranges - 0.5 litres/hour @ 21 bar to 94.6 litres/hour @ 2 bar with a turn down ratio of 100 : 1.

However, the Series E^Plus range offers additional features:-

• Clear hinged cover over controls for protection against water and dust ingress.


• *Optional External Pacing option - i.e. actuation via an impulse water meter - with stop function. The stop function accepts an input from a level switch in the chemical holding tank such that the pump will cease operating should the level switch indicate that the chemicals have run out.*Optional 4 to 20mA signal actuation with stop function. This offers the ability to accept a signal from an external piece of equipment - e.g. some boiler modulating feed valves emit a 4 to 20mA signal, which can be used to ensure that dosage of chemicals varies in direct proportion to the flow of water into the boiler.
  
  Dosage is lowest when the signal is 4 mA from the valve and highest when the signal is 20mA from the valve with a straight-line variation in between.


• Auto/Off/Manual selection switch with indicator lights.


• Built in circuit protection with easy access panel mounted fuse.

*Note; only one of these options - not both - can be utilised and must be specified at time of order.

Degasing Head Assembly

The Degassing Head Assembly is now a standard option available on the majority of PULSAtron pump ranges.  It is an effective solution to the problems often encountered with the dosage of oxidising chemicals such as sodium hypochlorite and chlorine dioxide.
