Precision Dosing Pump has automatic deaeration feature.
November 12, 2007 -
With ability to automatically degas pump head, Delta precision pump is suited for dosing fluids such as sodium hypochlorite. It offers continuous dosing of volumes as small as 5 ml/hr. Unit comes with relay module, solenoid valve, and optoGuard injection control system that detects air/gases locked in liquid end of pump. Models 2508 and 1608 offer capacities up to 7.5 and 7.8 l/hr at maximum backpressure of 25 and 16 bar, respectively.

New Versions of Delta Precision Dosing Pump Announced
ProMinent Fluid Controls, has announced an automatic deaeration version of its popular Delta precision dosing pump, together with two new models for the continuous dosing of volumes as small as 5 ml/hr. The new deaeration 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.
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 deaeration. Deaeration can also be set to occur on a regular basis. The new deaeration 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 addition to the Delta pump range, type 2508 and 1608 offer capacities up to 7.5 l/hr at a maximum backpressure of 25 bar 7.8 l/ hr at a maximum backpressure of 16 bar 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.
