Self priming pumps

Pneumatic diaphragm pumps of the hygienic series are made of polished stainless steel AISI 316L. The pumps are hermetically sealed, self-priming, and are designed primarily for pumping of slightly aggressive media, food and cosmetic products. They are used in those industries where there are increased requirements to hygiene, for example dairy production.

The vertical centrifugal pump is designed to submerge the pump in the pumped liquid so that the electric motor remains above the liquid level. The semi-submersible chemical pump uses special construction materials and technical solutions that allow it to withstand chemical attack not only from the inside but also from the outside. We offer sealed semi-submersible vertical pumps with magnetic coupling and pumps with mechanical seal for pumping sodium hydroxide and hypochlorite, sulfuric, hydrochloric, nitric acid, alkalis, various corrosive mixtures, solvent, wastewater with chemical impurities, etc.

FINISH THOMPSON is one of the leading manufacturers of barrel pumps and a specialist in centrifugal pumps in general. The range of drum pumps includes plastic and metal models used for emptying containers, barrels, tanks, medium-duty containers and hoppers. The range of centrifugal pumps includes stainless steel pumps, ETFE-coated process pumps, plastic pumps made of polypropylene and PVDF for aggressive, difficult chemicals.

The hygienic screw pumps are specially designed for use in the food, cosmetics and beverage industries. The pumps have a simple design, which greatly simplifies their cleaning. All metal parts in contact with the pumped product are made of SS304 / SS316 stainless steel. For the transport of materials with high viscosity, pumps with a wide discharge hopper are designed.

Electric metering pumps (piston and diaphragm) are designed for maximum operating ranges. Diaphragm and piston dosing pumps are specially designed for dosing all types of chemicals, whether corrosive, toxic or highly viscous, for water treatment, industrial processes, petrochemicals and agriculture. The main advantage of the pumps is the ability to connect up to four working heads to one motor, and these units can simultaneously pump different types of liquids with different capacities. The pumps themselves are made of high-quality materials, have a robust design and are maintenance-free.

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.

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 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 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.

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.

Peristaltic pumps of the N series (roller design) are self-priming peristaltic pumps with a seal-free design. The liquids are transported inside the hose and do not come into contact with any metal parts of the pump.

The pumps are characterised by extremely smooth pumping of the product, thus preventing the formation of emulsions or turbulence. All pumps can be supplied in monoblock versions connected to gearboxes, regulators, electric, diesel, pneumatic or hydraulic motors.

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.

Valisi metal pumps of the V series are available in a variety of construction materials: aluminium and stainless steel. This series of pumps for industrial applications provides high efficiency and reliability for continuous operation. With a flow rate of up to 908 l/min and a wide variety of materials and channel configurations, you will find the right pump for your application. FDA-compliant metal pumps are available, specially manufactured from materials that are safe for food, beverage, pharmaceutical and cosmetic processes where 3A, USDA or EHEDG standards are not required. The simple, robust design features trouble-free air valve operation, oil-free operation, reliable on/off operation, easy operation and maintenance, and delicate/shear-sensitive product handling. The pumps comply with EU Directive 1935/2004.

The SP series plastic centrifugal sealed chemical pumps with magnetic coupling are ideal for pumping aggressive liquids, various corrosive mixtures, solvent, wastewater with chemical impurities. The concentration of suspended solids should be no more than 1.25 mg/cubic cm. All pump components in contact with the medium are free of metal parts. Thus, no oxidation of the medium occurs in these pumps. The pumps are used even for media where contact with the atmosphere is not permitted.

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).

The Valisi VD-ECA series are diaphragm and piston metering pumps with advanced metering control for precise and automatic control. The pumps are designed to accommodate a variety of remote control options such as SCADA, etc.
