Double-acting pumps

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.

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 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.
