Pumps for Non-Newtonian fluids

Despite their simple design and operating principle, Valisi plastic diaphragm pumps are characterised by exceptional performance and reliability. They can be used to pump clean liquids with low viscosity as well as abrasive liquids with medium viscosity. In addition, these pumps can handle large particles without damaging the equipment. And thanks to the pneumatic motor, they can be used in explosive atmospheres.

DELLMECO air-operated diaphragm pumps (AODD) are suitable for a wide range of applications. They have high abrasion resistance and can withstand aggressive chemicals, including acids, oils, solvents, paints, sludge and even media containing solid particles, such as in wastewater. These pumps can also be used for pumping powders.
All pumps are self-priming and their performance and pressure can be easily controlled. This pump is a positive displacement pump that pumps liquids by the movement of diaphragms driven by compressed air. The casing in contact with the liquid is made of polyethylene (PE), polyethylene conductive, polytetrafluoroethylene (PTFE), polytetrafluoroethylene conductive.

The modern metal  diaphragm pump of VC series features a unique, non-jamming air valve that is simple, robust and reliable, and does not require a separate or mechanically operated pilot valve. The bolted design ensures leak-free pumping of liquids. The pneumatic diaphragm pumps are designed and manufactured to meet the needs of both OEMs and end users. The main characteristics of these pumps are competitive prices, few parts, simple design and maintenance, and high quality. Stainless steel pumps are FDA approved. Aluminium pumps with PTFE diaphragms are explosion-proof and ATEX certified.

Rotary Lobe Pumps are reliable and efficient solutions for pumping liquids in a wide range of industries that require reliable and wear-resistant technology.

Rotary Lobe Pumps are reliable thanks to its hygiene design, capable of pumping without damaging liquid’s structure, and depending on liquid’s viscosity, Rotary Lobe Pumps have the ability of generating pressure up to 12 Bar.

The VPH series of peristaltic pumps with shoe technology is our updated peristaltic pump designed for high pressure applications up to 15 bar, with 14 sizes available in flow rates up to 150 m3/h. This is a heavy-duty industrial pump series designed for round-the-clock operation. We have combined the best available materials with clever design solutions to maximise uptime and minimise maintenance.
This pump summarises what we want to achieve: the best pumping solutions for our customers. Our design increases the simplicity and reliability of the pump.

VALISI internal gear pumps of the VD series are positive displacement pumps with a robust and simple design (only two moving parts). This type of design allows for efficient pumping of both liquid and clean media, as well as highly viscous abrasive media with inclusions (e.g. asphalt, chocolate, honey, etc.). The pumps can pump liquids with a viscosity of 100 ~ 1.000.000 cst. The pumps provide a uniform flow and high pressure. The following gear pump designs are available: without axial support, with axial support, in-line design, monoblock design, and high-speed design.

Idrochemical NCM centrifugal pumps comply with the dimensional criteria of ISO 2858 and ISO 5199. The casing and impeller profiles are designed to achieve high hydraulic efficiency and low NPSH.

The NCM line is available in five bearing housing sizes with wide interchangeability of parts, which allows for low maintenance spares.

The non-self-priming plastic centrifugal hermetic chemical pumps with magnetic coupling of the DB series are one of the most popular chemical pumps in the pump segment with a capacity of up to 50 m3/h. The pumps are ideal for pumping aggressive liquids such as sodium hydroxide and hypochlorite, sulfuric acid, hydrochloric acid, nitric acid, alkalis, various corrosive mixtures, solvent, wastewater with chemical impurities. The concentration of suspended particles should not exceed 1.25 mg/cubic cm.

The pumps are used in various enterprises, industries, in the most difficult operating conditions, ensuring smooth fluid transfer. The pumps are suitable for pumping liquids with low and high viscosity, as well as for pumping abrasive, sticky, crushing and foaming liquids. The pumps are particularly suited for handling products with solid particles. The suction capacity is max. 5m/s. The pumps deliver regular, linear, pulsation-free and measured flow. Quiet operation without vibration.

The design of the pumps allows them to be used for many different applications. The standard design includes an enlarged rectangular inlet hopper with a screw conveyor that pushes the product to be pumped into the pump's working section. There are versions in which the pump inlet is equipped with a large screw, an integrated cork breaker or both. Most pumps are supplied in a monoblock design (direct connection of the pump to the electric motor) or with a free shaft outlet (without an electric motor).

Reduce energy consumption and lower maintenance costs with Wanner Hydra-Cell T & Q series, a triplex multi-diaphragm pump (three-piston) or a quintuplex (four-piston) diaphragm pump. These seal-less and packing-free pumps meet API 674 standards and are designed for heavy-duty applications for process, transfer and injection for the oil and gas industry.

The Wanner Hydra-Cell G-Series process pumps are highly efficient and reliable for transferring corrosive, non-lubricating and abrasive liquids, injecting and spraying a wide range of fluids. The pumps are equally suitable for high and low pressure applications. The sealed design reduces maintenance and repair costs and minimises the cost of spare parts compared to other pump types. The pumps are available with SAE, ANSI or DIN flanges and IEC or NEMA motor mounts. The equipment is ATEX certified.

W+ is a comprehensive range of premium sanitary end-suction centrifugal pumps designed with maximum operating benefits and minimal life cycle costs in mind. Energy-saving sanitary centrifugal pumps of the W+ series are characterized by increased reliability and a high level of hygiene. The pump series consists of 17 standard models.
