Pumps for Light 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.

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.

The SANDPIPER Non-Metallic AODD Pumps for standard applications are one of the most popular diaphragm pump series. The pumps are available in a wide range of sizes (1/4'' - 3''), casing materials and elastomers. The pumps are most commonly used in production areas where aggressive and explosive liquids need to be pumped. Due to their light weight, these pumps are used in portable versions for pumping liquids from drums.

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 AVPL oil rotary lobe pumps are extremely compact thanks to their integrated motor and transmission, making them the ideal choice for compact installations. They are equipped with extremely robust blades that ensure a long service life. Specially designed oil filters ensure excellent oil separation, removing even the smallest oil droplets from the exhaust air.

The AVA series pumps are designed and manufactured for use in the most critical applications, their main feature being that they are suitable for suction of contaminated gas mixtures, corrosive gases and vapours, explosive gases and vapours of any nature up to normal end vacuum, providing a maximum vacuum of up to 180 mbar. They are manufactured to the highest quality standards.

Dry operated rotary vane pumps designed to operate without any lubrication. They require minimum maintenance, which can be carried out easily thanks to the direct access to the vanes. They can be used as vacuum pumps, as compressors, or to produce vacuum and pressure simultaneously.

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.

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.

Hydra-Cell Metering Solutions pumps meet and, in most cases, exceed API 675 performance standards by providing virtually pulse-free, linear flow, as well as many other operational benefits. Taking advantage of state-of-the-art technology, Hydra-Cell P-Series metering pumps achieve superior levels of accuracy, repeatability and linearity, delivering precise, consistent flow. This revolution in metering uses the latest electronic flow control available to replace outdated, inaccurate stroke controllers.

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.
