Twin screw pumps for food applications

Wednesday, March 21st, 2018 von admin

Hyghspin twin screw pumps have a compact design and many versatile and flexible uses. The design of these pumps do follow hygienic design criteria. Their block construction saves space and always ensures a correctly aligned coupling.

Mobile units including frequency converter and service switch are another feature of this pump range. These units stand out, among other things, on account of their self-priming qualities and ease of service. Safe-to-run dry seals, for example, require no flushing.

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.

Lewa: New Triplex process diaphragm pump

Thursday, June 25th, 2015 von admin

abb1The G3M, a heavy-duty, medium-sized triplex drive unit, was originally developed to bring re-liquefied boil-off gases from LNG tankers to a high pressure level, rendering these gases usable for the ships’ propulsion system. As a rugged workhorse, it is also ideal for various other applications, including use in the chemical industry or for offshore applications on oil platforms. The Lewa Triplex G3M process diaphragm pump was one of the main exhibits of Lewa GmbH at Achema 2015.

The G3M is an intermediate size product in the Lewa portfolio that attains a maximum output of 200 kW thanks to its stroke length of 120 mm and a rod force of 125 kN. It is intended for use primarily in the oil and gas industry, as well as the chemical process industry. The chief application in the former sector is injecting monoethylene glycol and methanol. In the process industry, a wide variety of pumping tasks in pressure ranges between 40 and 750 bar can be managed. Other possible applications include handling highly flammable materials such as vinyl acetate, slurry in the wet oxidation or high-pressure metering of liquid ammonia.

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.

Magnetic Couplings Seal New Zero-leakage API 685 Refinery Pump

Wednesday, January 15th, 2014 von admin

MAK 685 KSBKSB South Africa in cooperation with EagleBurgmann specified high-efficiency magnetic couplings to seal the shaft for the newly designed API 685 process pump. It was also decided to use the couplings from the proven MAK685 series because they reliably cover a broad application field in the higher pressure and performance range.
