New Delta precision dosing pump models
ProMinent Fluid Controls announces 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 5ml/hr
The new 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 ideally suited to dosing fluids which easily outgas, such as sodium hypochlorite

New motor driven dosing pump completes the range
ProMinent Fluid Controls has introduced the Sigma/1 motor driven precision dosing pump to complete the comprehensive Sigma series range, now covering 17 to 1030 L/hr
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 new de-aeration facility can be field- -fitted to existing Delta pumps.
The Delta pump is controlled using the novel '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.
Two new additions to the Delta pump range, type 2508 and 1608 offer capacities up to 7.5L/hr at a maximum backpressure of 25bar 7.8L/hr at a maximum backpressure of 16bar respectively.
The 2508 versions are available with an acrylic or stainless steel liquid end.
The 1608 version is available with acrylic, PVDF or stainless steel liquid ends.
