Valisi V series metal diaphragm pumps

Valisi V Series Metal Pumps

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

Characteristics of Valisi metal pumps

Side inlet/outlet ports: NPT and BSP thread options for stainless steel, aluminum and cast iron models. Center flanges are also available for some sizes.

Housing construction materials: A choice of aluminum, cast iron, hastelloy or stainless steel is available for increased durability and corrosion resistance in the most challenging environments and processes.

Durable pleated diaphragms: service life of pleated diaphragms can be 4 times that of conventional diaphragms.

Materials used for the central part of the pneumatic system: Centerpieces made of glass-filled polypropylene, aluminum or all stainless steel are available for optimum corrosion protection and compatibility.

Options: Stainless steel air motor and pump body bolts for complete corrosion protection.

Advantages of V-Series Metal Diaphragm Pumps

• Pneumatic diaphragm pumps are designed for general use. They can easily pump both clean fluids of low viscosity and abrasive fluids of medium viscosity, and can carry large particles without damaging equipment. 
• Thanks to the air motors, they can be used in a potentially explosive environment.
• Most V series diaphragm pumps are ATEX certified (CE Ex11 2GD X).
• They are also self-priming up to a height of 8 m  (for water) and can run dry without risk of damage. If the liquid outlet is closed, the pump stops. It restarts when the nozzle is opened; this eliminates the need for a safety or relief valve.
• Large pumps we offer allow for changing the volumetric flow rate from one liter per minute to 908 liters per minute at the outlet, as well as adjusting the fluid pressure from 0 to 8 bar only through the use of an air filter/regulator and a needle valve.
• Pleated diaphragms are used in all pumps to ensure longer service life and reduce periodic maintenance.
