1/2” AODD pump with multiple mounting orientations

Friday, November 16th, 2018 von admin

The new V150 13 mm (1/2”) Velocity Series pump from Wilden is featuring a detachable mounting foot. It can easily be reoriented into a vertical or horizontal position with multiple inlet and discharge port options. With this innovative design, the pump can be installed in multiple orientations, a critical consideration for systems and skids.

The Velocity Series – available in 13 mm (1/2”) and 6 mm (1/4”) sizes – features a bore-seal design that eliminates leaks that can result from torque decay. It also delivers improved dry suction lift up to 4.3 m (14.2’) in the 6 mm (1/4”) size and 5.1 m (16.9’) in the 13 mm (1/2”) size better priming. In addition, these pumps incorporate a proven and simple air distribution system (ADS) with only two moving parts that reduces the risk of downtime for long-term reliability.

Protecting pumps in hazardous areas against dry running

Monday, November 12th, 2018 von admin
  • New type of active power-based dry running protection for pumps with certification according to Atex and IEC Ex
  • Current/voltage detection modules for the Simocode pro motor management system
  • Previously required additional sensor technology is eliminated
  •  Higher levels of system availability and economic efficiency.

A new type of detection technology from Siemens protects centrifugal pumps from dry running in hazardous areas. For this purpose, the corporation has developed special current/voltage detection modules for its Simocode pro motor management system.

Pumps for the ISS

Wednesday, October 24th, 2018 von admin

Liquid pumps made by KNF were on board an HTV-7 unmanned cargo spacecraft launched from Japan on September 23, 2018, destined for the International Space Station (ISS). These space-worthy liquid pumps are part of a new Life Support Rack for the ISS. Also known as an Advanced Closed Loop System (ACLS), the rack purifies air and produces oxygen for the ISS. It was developed by Airbus Defence and Space for the European Space Agency (ESA). The new ACLS rack will be installed in the ISS’s Destiny module (also known as the US Lab) by ESA astronaut and ISS commander Alexander Gerst on November 2, 2018.

KNF-Engineers worked with Airbus for four years to specify and design the pump, which is based on the proven FEM 1.09 dosing pump. The project was part of Airbus’s COTS (commercial off-the-shelf) program, which uses well-established components to reduce the price tag for space flight.

Mobile horizontal eccentric screw pumps

Thursday, October 18th, 2018 von admin

The B70H is a variation of the B70V by Lutz and is designed for the horizontal use on a trolley. It can be used in situations where the B70V comes across space limits or limits of handling and thus completes the range of eccentric screw pumps with a mobile version.

New series of Low Energy Air Diaphragm Pumps

Tuesday, October 16th, 2018 von admin

Tapflo named its new pump series “TC Intelligent pumps”. The main step forward is the LEAP technology – ‘Low Energy Air Pump’. This is a patented technology used in AODD pumps to reduce the minimum operating air pressure by reducing internal losses and friction.

“LEAP uses an indirect system to detect the position of the diaphragm shaft controlling the diaphragm movement automatically”, explains Colin Wreyford Technical Director at Tapflo.

4 Reasons to choose AODD pumps for chemical processes

Thursday, September 20th, 2018 von admin

Technical paper by Erik Solfelt:

Thanks to its simple yet innovative design, the AODD pump has proven to be able to consistently meet the demands of chemical processors while building a reputation as a go-to pumping technology where basic fluid-transfer capabilities are required. The AODD pump, which possesses a stable of notable operational characteristics, has become a first-choice technology for chemical manufacturers who are searching for a pump that meshes cost-conscious air consumption with reliable and safe production rates.
