The de-aeration facility makes the Delta the only pump of its kind which can automatically degas when gas is detected in the pump head.
ProMinent Fluid Controls has released an automatic de-aeration version of its popular Delta precision dosing pump, together with two new models for the continuous dosing of volumes as small as 5mlitres an hour.
The de-aeration facility makes the Delta the only pump of its kind which can automatically degas when gas is detected in the pump head.
This makes it suited to dosing fluids which easily outgas, such as sodium hypochlorite.
The Delta pump features the optoGuard integrated injection control system, which detects air or any gases locked in the liquid end of the pump that could prevent dosing of the correct quantities.
The addition of a special relay module and solenoid valve attached to the coarse/fine bleed valve of the pump allows the airlock detected signal to trigger automatic de-aeration.
De-aeration can also be set to occur on a regular basis.
The de-aeration facility can be field- fitted to existing Delta pumps.
The Delta pump is controlled using the optoDrive system.
By monitoring the actual diaphragm displacement with its predicted displacement and compensating for possible backpressure fluctuations, optoDrive allows a slow-pressure output stroke to be set for almost continuous dosing or a fast stroke to be set for pulsed dosing.
The 2508 and 1608 versions offer capacities up to 7.5 litres an hour at a maximum backpressure of 25bar or 7.8 litres an hour at a maximum backpressure of 16bar, respectively.
The 2508 version is available with an acrylic or stainless steel liquid end.
The 1608 version is available with acrylic, PVDF or stainless steel liquid ends.
