Pumps and Valves

Due to customers requests, Larox Flowsys introduces a basic version of its LPP-M pump in addition to the current smart version. Whereas the current version contains multiple automatic input/output control and alarm modes the new basic version will have only single manual output control mode. The technical features such as the flow rate, pressure and suction lift remain the same, but programmabilities such as remote adjustment and different feedback signals are left out from the basic model.

Larox Flowsys has launched a new series of valves to supplement the pinch valve family. Larox Heavy Duty Knife Gate Valves are engineered to be used in tough environments with demanding media in the same industrial applications as company's well known pinch valves.

Burkert has supplied a Robolux valve system on a machine that fills asthma inhaler cartridges for a multinational pharmaceutical company. The unique Robolux design has enabled Burkert to reduce the costs of the system drastically, by cutting the valve requirement from eight diaphragm valves down to four. In addition, because Burkert’s integrated design has only one block – compared to two for competitors - there are fewer weld connections for the customer to make, reducing installation time and validation costs; and the integrated design also means that internal volumes are smaller, eliminating deadlegs and maximising sterility.

Isolated miniature solenoid valves (IMSV) that provide maximum power from a minimum sized envelope are the current demand of original equipment manufacturers (OEMs) in the field of laboratory and analysis technology, and also medical engineering. In clinical diagnostics, flow-rate and reliability are essential, while cleanliness is given top priority. In automated analytics, standard procedures such as titration, defined sampling and the precise dosage of reagents, based on integrated fluid control systems, require pinpoint precision and repeatability. In addition, manufacturers and users, when opting for a certain type of IMSV, also consider cost, wetted material type, cleanability, dosage capacity and flushing characteristics of the valve.

Burkert’s Robolux valves have eliminated deadlegs and reduced the requirement for diaphragm valves from 8 to 2 on sterile filling units used in the production of Pulmicort, one of the world's leading asthma medicines. The Robolux valves have also greatly simplified the design of the filling units, cutting cycle times and making maintenance and cleaning procedures far easier to carry out.

Netzsch Pumps Ltd have supplied two of their NM063SS01L06B pumps to Ancillary Components Ltd in Northampton to replace standard progressing cavity pumps to offer improved service life feeding the Goosey Lodge Power Plant.

Diversified industrial manufacturer Eaton Corporation announced today that it has added a new Series 760 variable displacement closed circuit piston-type pump and fixed motor to its heavy-duty product offering. Intended primarily for mobile vehicle applications, the new pumps and motors are available with displacements of 130cc/rev at 3200 rpm operating speed, and 160cc/rev at 2950 rpm operating speed. Working pressure for both displacements is 430 bar, with a high pressure relief setting of 465 bar for the pump. Both pumps and motors have a SAE D-flange mount.

Aalborg’s new Model TPU Adjustable Speed Tubing Pumps’ chemically resistant tubing materials and new peristaltic pump head technology combine to meet the demands for reliable, long-term pump operation. Four stainless steel rollers minimize pulsation and promote longer tube life.

Aalborg has announced the release of its VT6 6mm orifice PTFE Needle Valves for corrosive liquids and gases. Simplicity of design (only 6 components) assures minimal sources of leakage, quick disassembly, and easy maintenance.

Aalborg’s new Model TPU Variable Flow Tube Pumps are ideally suited for liquids of low to medium viscosity. Chemically resistant tubing materials and new peristaltic pump head technology combine to meet the demands for reliable, long-term pump operation. Four stainless steel rollers minimize pulsation and promote longer tube life.
