Interface devices to connect pumps

as small as 150 microns, selflubricating internal components with low start-up torque and a one-piece polished stainless steel rotor shaft.
The 49 x 75 x 86 mm selfpriming rotary vane pump is technically similar to standard models with fewer components and can be matched with a small motor to replace vibration pump units and installed in any position.
The pump has an 18 bar maximum working pressure and handles fluids up to 50°C as standard or 90°C as special.
The pump has five flow rates between 50 and 270 l/m at 1400 rpm with or without normal or balanced by-pass and adjustable maximum pressure. It features an optional built-in 100 mesh stainless steel filter which can removes particles

Interface devices to connect pumps WILO AG has developed a range of new interface devices which make it possible to connect communicable heating and circulating pumps to a central building control station according to the needs of the user. The devices, called WiloAnaCon, Wilo-DigiCon and Wilo-DigiCon-A can replace the analogue and digital interface converters which are currently available. They form an part of the company’s Wilo Control system and can connect the the Wilo series Stratos/Stratos-Z/StratosD, TOP-E/ED, Crono-Line-IL-E, CronoTwin-DL-E, VeroLine-IP-E and VeroTwin-DP-E. Wilo says that installation is safe with asimple wiring to the pump.
Dosing pump can automatically degas ProMinent Fluid Controls has developed an automatic deaeration version of its 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, Prominent says, making it suitable for dosing fluids which easily outgas, such as sodium hypochlorite. The Delta pump features the company’s optoGuard integrated injection control system, which detects any air or gases locked in the liquid end of the pump that could prevent
the dosing of the correct quantities. Adding 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, which can also be set to occur on a regular basis. The new deaeration facility can be fieldfitted to existing Delta pumps. The Delta pump also features the optoDrive system which allows a slow pressure output stroke to be set for almost continuous dosing or a fast stroke to be set for pulsed dosing by monitoring the actual diaphragm displacement with its predicted displacement and compensating for possible
backpressure fluctuations. The 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 and 7.8 l/ hr at a maximum backpressure of 16 bar. 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.

wastewater treatment plants and their remote facilities. TopView 6.0 software can monitor thousands of process measurements and users can create custom messages for each tag point, so personnel can receive a detailed description of
the problem as well as its exact location. Remote access and acknowledge communication is supported through dial-in phone, PC, and Windows Mobile devices, so personnel can easily interrogate the status of a specific measurement at any time from any location.
Low-flow pumps for biotechnology
The miniature low-flow HNP pumps for biotechnology.
A new range of miniature, ultra low-flow, positive displacement, micro annular gear pumps is now available from Michael Smith Engineers. The ultra-compact HNP series of pumps deliver liquids with a precision of CV <1% across a range of flow rates from 0.25 ml up to 1152 ml/m, and are suitable for OEM, analytical, biotechnology and other similar applications. The range comprises four series of pumps with dosage volumes covering the sub-micro litre to litre range for both non-lubricating and highly viscous liquids. The HNP micro annular gear pumps are rotary pumps constructed with an externally toothed internal rotor and an annular tooth external rotor, which are slightly eccentric to each other. During rotation of the rotors around their offset axis, the pumping chambers simultaneously increase on the suction side and decrease on the delivery side of the pump, resulting in a homogeneous flow rate being generated between the kidneyshaped inlet and outlet. The pumps also have high differential pressures up to 150 bar for some models and long-service life due to the use of materials such as wear-resistant tungsten carbide and ceramics. Typical applications include micro-process and microreaction systems, analytical instrumentation, sampling, robotics, fuel cells, particle and DNA analysis, biological cell handling, ink jet printing, minimum quantity lubrication systems, aromatizing, flavouring, PCB cooling and process intensification systems.
