Verderpro VPD dosing pump; accurate dosing, low pulsation

Dosing viscous liquids requires a specific pumping solution. Many well known dosing pumps are not suitable for a viscosity of more than 1000 cP or need specific adaptations.
The Verderpro VPD can handle high viscous liquids, even with solids, with a dosing accuracy of less than 1%.
The VPD dosing pumps are non-pulsating (low pulse) progressing cavity pumps and dose fluids from low to high viscosity. The lack of pulsation makes it easy to measure and control the flow. These features make the VPD progressing cavity pumps the ideal pump for dosing applications

Applications for Verderpro dosing pump

• waste water and sludge treatment
• textile industry (dosing dyestuff)
• paper industry (glue, kaoline and colorants)
• fruit and vegetable processing (apples, strawberries, tomatoes)

Advantages and features

The Verderpro VPD comprises 4 subtypes, each with specific advantages and features. Flow rates up to 1000 l/h and max backpressure up to 24 bar.

VPD type

• Close coupled, short and compact construction
• Easy maintenance through pin shaft

VPDR for high viscous products

• Feeder with conical/cylindrical compression zone
• Coupling rod with screw pitch

VPDH/VPDHR hygienic dosing pump for viscous, non-fluidising products

• 3A Sanitary and FDA approved
• Extremely anti-corrosive and wear resistant (rotor AISI 316 Ti, stator silicone light)
• Newly designed open pin coupling consisting of only two elements for higher pressure and better flow rates

The importance of seals

The selection of seals is strongly depending on the dosing application and medium. For the shaft seal you can choose for a single or double mechanical seal or a mechanical seal with quench, especially for adhesive products.
