Are there any corrosion-resistant shielded pumps? Our materials are slightly corrosive, and the shielded pumps break down frequently; please help, experts.
Provide the material composition, temperature, viscosity, specific gravity, flow rate and head, as well as inlet and outlet pressures. Only then can it be determined whether it is corrosion or a mechanical failure.
It’s corrosion; the material has a weak acidity, and both the impeller and the shielding sleeve are corroded
Let’s switch to a magnetic pump. Please provide information on the medium, temperature, and the net positive suction head available at the installation, and we’ll prepare a proposal for you.
Both shielded pumps and magnetic pumps come in corrosion-resistant and high-temperature resistant versions; it depends on your choice.
Magnetic pumps can’t handle high pressure, right? Our outlet pressure is 16 kilograms
The material of the pump’s flow-through components can be improved to an anti-corrosive material
It’s only 1.6 MPa – there’s no problem at all. In multi-stage magnetic pumps, the magnetic coupler is located on the inlet side.
You didn’t choose the right model; either the material doesn’t meet the requirements, or the pressure isn’t very high, so there should be no problem
The shielding sleeve of shielded pumps is generally made of Hc-276; what if corrosion still occurs? If there is a problem with the material of the shielding sleeve, it is necessary to determine whether the issue lies with your medium or with the materials used in the equipment.
