ProMinent: New hydraulic diaphragm metering pumps

Tuesday, August 11th, 2015 von admin

Evo-1-4_Gruppe_transparent (2)The hydraulic diaphragm metering Orlita Evolution form an integrated product range with stroke lengths of 15 to 40 mm. This covers the capacity range from 3 to 7,400 l/h at 400 to 10 bar. A wide range of drive versions is available, including some for use in Ex-zone 1 and 2. The Orlita Evolution product range is designed to comply with API 675. This pump serie meets the most exacting safety requirements as an extremely robust hydraulic diaphragm metering pump. It stands out thanks to its PTFE multi-layer diaphragm with integral diaphragm rupture warning system and unique diaphragm position control. Its modular construction offers extremely good flexibility in terms of applications.

Neptune: Metering pumps in irrigation systems

Wednesday, February 11th, 2015 von admin

Neptune_Chemigation-30These systems have been designed for the application of fertilizers, herbicides, fungicides, insecticides and other strong chemicals. The chemical tanks have a sloped bottom for complete drainage and ease of cleaning. All tanks larger than 55 gallons are fitted into double-wall containment and with double wall injection lines to protect the environment. A cover shields the pump, piping and electrical controls from the elements and excludes rain and debris, which allows 100% reclaim of uncontaminated chemical in the event of a spill or broken line.

Lewa: Hermetically tight 170 °C high-temperature pumps for production

Wednesday, December 17th, 2014 von admin

Wacker_freiIn the existing chemical installation in a Wacker Chemie plant, the safety-related design of the relevant pump systems had to be thoroughly renovated. One of the basic requirements for the redesign was that diaphragm pumps themselves had to remain absolutely hermetically tight, even at high working temperatures of +170 °C during normal operations and brief peaks as high as +200 °C. As a result, Lewa developed an individual solution to meet the specific customer requirements.

“As an additional security measure, the pressure-free hydraulic reservoir behind the diaphragm is blanketed with nitrogen as a protective gas”, explains Lewa project lead Rainer Sonnenfroh.
