Pumps for Bitumen

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.

General purpose pumps are widely used in all areas of industrial production around the world due to their gentle handling of the fluid during pumping, as well as their simple and robust design and minimal maintenance. Thanks to the standard connection dimensions, the pumps can be combined with any motor and other drive elements that comply with NEMA or IEC standards.

Heavy-duty gear pumps solve the toughest applications and ensure maximum flow rates when emptying large tanks. The foot-mounted design of the pump allows the use of various types of mechanical seals without changing the design of the pump itself (Universal Seal series). A large bearing cup located at the rear of the pump allows the installation of any seal, from a conventional stuffing box to a double mechanical seal.

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).
