Wilden: New Diaphragms for Industrial Applications

Monday, May 22nd, 2017 von admin

The new Chem-Fuse diaphragms are specifically designed for industrial applications. The Chem-Fuse diaphragm technology eliminates the potential leak point at the outer piston as well as outer piston abrasion. This is crucial for industrial applications that pump abrasive or dangerous fluids. The diaphragm design also offers easy cleanability for faster changeovers between products. These features allow Chem-Fuse diaphragms to enhance productivity, reliability and safety.

An additional benefit of Chem-Fuse diaphragms compared to other reduced-stroke integral piston diaphragms is the use of a large integral piston and full-stroke shaft that provides greater efficiency. This design allows Chem-Fuse diaphragms to provide up to 100 % increased flow and suction lift compared to other diaphragms.

Flotronic: The One-Nut Design for hygienic AODD

Tuesday, March 28th, 2017 von admin

UK specialist pump manufacturer Flotronic Pumps Limited was founded by Lew Norris in 1981. The engineering design consultancy ‘Norris Brothers’ had been involved in the design of  specialist pumps since 1952.  Lew Norris’ new company pioneered the air-operated, double-diaphragm ‘One-Nut’ pump. Flotronic’s ‘One-Nut’ design allows quick pump disassembly for inspection, cleaning and maintenance – delivering a massive benefit for pump users in terms of reduced down-time, particularly as the pump can be inspected or maintained in line without disconnection of pipework. Flotronic remains the only British-owned specialist manufacturer of air-operated, double-diaphragm pumps in the UK.

Wilden: Pure-Fuse diaphragms for hygienic applications

Tuesday, March 1st, 2016 von admin

Wilden_Pure-Fuse-DiaphragmPure-Fuse diaphragm technology incorporates a one-piece design that eliminates product-trap areas between the outer piston and diaphragm that can harbor bacteria, a critical consideration for hygienic applications. This patented design also provides an unbroken fluid-contact surface for CIP capability and reduced contamination risks. Pure-Fuse combines food-grade plastics and elastomers with a stainless-steel core using no adhesives or nylon fabric that can contaminate process fluids in the event of a breech. In addition, by eliminating the outer piston Pure-Fuse diaphragms experience reduced abrasion, which results in longer diaphragm life.

Wilden: High pressure AODD with energy-efficient air distribution system

Monday, October 26th, 2015 von admin

Wilden_SHIFT-High-Pressure_familyThe two new 1-1/2-inch (38 mm) high pressure bolted metal AODD pump models feature redesigned liquid paths to reduce internal friction to maximize output and efficiency. They are shear sensitive, dry-run capable, externally serviceable, completely submersible and comply with all CE and Atex requirements. These pumps also come equipped with the Pro-Flo Shift air distribution system.

The two new high pressure pump models are

  • the HS400S, which is available in aluminum, and
  • the HS430S, which comes in stainless steel.

Flotronic: New ‘E’ Series’ achieves EHEDG seal of approval

Monday, September 14th, 2015 von admin

EHEDG Series pump cutoutFlotronic Pumps Limited, the UK-based specialist manufacturer of air-operated double diaphragm pumps, having already secured 3-A Sanitary Standards, Inc (3-A SSI) approval for their ‘H’ series pump, have now achieved the European Hygienic Engineering & Design Group (EHEDG) accreditation for their new ‘E’ Series pump.

The ‘E’ Series pump has been specifically designed for the Food and Beverage industry and other processes where product contamination must be avoided. The pump’s features include Flotronic’s established and unique ‘One-Nut’ pump design which allows swift diaphragm access without disconnecting process pipework. The internal surfaces of the ‘E’ Series pump can be effectively ‘cleaned in place’ or, alternatively, easy dismantling can be carried out for cleaning and inspection. Cleaning is aided by the provision of polished wetted surfaces to 0.8μm Ra maximum and an electro-polished overall finish. Cleanability is also assisted by the incorporation of a support stand whereby the pump can be inverted for full draining.

Almatec: Flexible choice of product connections

Monday, April 20th, 2015 von admin

Almatec_CXM_BildThe new Almatec air-operated diaphragm pump series CXM – shown at Achema 2015 –  consists of four sizes and can be equipped with seven different product connections. This is possible thanks to the modular design of the pumps. For each pump of the sizes 20, 50 and 130 two center blocks are available with different connection types and sizes.

This wide range of product connections allows a precise adjustment of the pump to the specific application. This is reinforced by the alternative choice between a ball and cylinder valve system, which can also be converted to each other. Ball valves are ideal for liquids containing particles, cylinder valves for superior suction lift.
