Self-priming Centrifugal
Chemical Pump
Chemical transfer pump
Thermoplastic casing, up to 25 m³/h
VGA series elastic coupling, self-priming pumps are designed for loading and unloading pools, tankers, tanks. It can feed from a maximum negative suction height of 4 meters without the need to fill the first feeding chamber.
Application
Sulfuric Acid (H2SO4), Hydrochloric Acid (HCl), Sodium Hypochlorite (NaOCl), Nitric Acid (HNO3), Caustic Soda (NaOH), Phosphoric Acid (H3PO4), Ferric Chloride (ZnCl2), etc.
Construction
The parts in contact with the liquid are made of plastic block (PP, PVDF, PVC, PE), and the gaskets are made of (EPDM, FPM).

Construction Material
Chemical transfer pumps are manufactured from materials with high chemical and mechanical resistance such as PP, PE, PVDF, FRP.
PP
PE-UHMW
0/+90 °C
-30/+90 °C
Polypropylene (PP) is a thermoplastic polymer used in a wide variety of applications. It has high mechanical and temperature resistance.
Ultra-high molecular weight polyethylene (UHMWPE, UHMW).
It provides very high chemical and mechanical resistance.
PVDF
-20/+120 °C
-20/+120 °C
FRP
Polyvinylidene difluoride (PVDF) is a thermoplastic fluoropolymer.
PVDF is a specialty plastic used in applications requiring resistance to solvents, acids and hydrocarbons.
Fiber reinforced plastic (FRP; Fiber reinforced plastic) is a composite material made from a polymer matrix reinforced with fibres.
It is used in processes requiring mechanical and chemical resistance.
