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.

Construction
01
S235JR-EN1025 extra thick front metal armor.
02
PP, PVDF or PE-UHMW construction.
03
Centrifugal impeller made of PP, PVDF or PE-UHMW; semi-open model for particle-laden fluids and closed model for pumping high-temperature solutions.
04
Manufactured in one piece, the shaft sleeve is made of PP, PVDF or PE-UHMW. It completely covers the part of the steel shaft in contact with the process fluid and rotates with the impeller, although it is independent of it.
05
Standardized mechanical seal selected based on plant and process requirements.
06
S235JR-EN1025 Extra thick front metal armor made of carbon steel.
07
S235JR-EN1025 Discharge flange made of carbon steel, consisting of two parts.
08
Shaft made of 42CrMo4 Carbon steel (special alloy on request), designed to support torsional and radial forces; Protected by a precisely machined shaft sleeve made of PP, PVDF or PE-UHMW.
09
Intermediate adapter made of cast iron. A unique part designed to separate the electric motor from the main pump.
10
S235JR-EN1025 or SS316 base plate.

Mechanical Seal
The elastomeric bellows seal is a mechanical seal designed for moderately corrosive, clean and not extremely hot liquids. It consists of static and rotating rings made of SiC; The spring and armor are made of SS316 and are not in contact with the process fluid. Elastomeric bellows are made of EPDM or FPM. This seal is available in external (B6E – B6EC), internal (B6I – B6IC – B6IH) and double flush (B6EDF – B6EDFC) types.
PTFE bellows seal is a mechanical seal designed for highly corrosive fluids and high temperatures. It has static and rotating rings in three different combinations (SiC-SiC, SiC-Al2O3, Al2O3-PTFE-C); It has PTFE bellows, springs and SS316 armor that does not come into contact with the pumped liquid. This seal is available in external (JRS – JRS1 – JRA) and double flush (JR2S – JR2S1 – JT2P – JR2A) types.
The elastomeric O-Ring seal is a mechanical seal suitable for moderately corrosive, clean and not extremely hot liquids. It consists of static and rotating rings in two different combinations (SiC-SiC, Carbon-graphite-SiC); bow and armor are Hastelloy C276. The O-ring is made of EPDM or FPM. This gasket is available in internal (UMG – UMS) and double flush (UM2G – UM2S) types.
