-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
In the 65-125 and 65-160 series, the body is made of machining from PP or PVDF blocks, and in the 25-125, 32-125, 40-130, 40-160 and 50-160 pump models, the body is injection molded.
02
Centrifugal impeller made of PP or PVDF; It is offered as a semi-open model for particle-laden fluids and a closed model for pumping high-temperature solutions.
03
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.
04
Standardized mechanical seal selected based on plant and process requirements.
05
Intermediate adapter made of thermoplastic material from 25-125 to 65-160 and cast iron from 32-200 to 125-250. A unique part designed to separate the electric motor from the main pump.
06
Shaft made of 42CrMo4 Carbon steel (special alloy on request), designed to support torsional and radial forces.
07
Flanges made of glass fiber reinforced PP, internally reinforced with steel.
08
S235JR-EN1025 or SS316 chassis.

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.
