Magnetic Pumps, manufactured by Jiangsu Tengyu, offer advanced technology for the safe and efficient transfer of chemical liquids. The model number CQF represents our commitment to quality and reliability in the Chemicals product group.

Magnetic drive
Magnetic drive centrifugal pumps are Seal-less. The driving torque is transmitted by a permanent
magnetic coupling to an internal magnet that moves the impeller. They are energy efficient and can circulate a variety of fluids.

No leakage
Magnetic drive pumps (like most sealless pumps) have a higher initial costs than comparable centrifugal
pumps, but offer reduced operating costs thanks to the lack of seal replacement, cleanup, waste, and
downtime. They are particularly useful for transporting hazardous or expensive chemicals because there is no mechanical seal, eliminating the possibility of leakage.

Construction
Many years of experience resulted in this latest design in pump technology. The fluid section is sealed by solid plastic parts and the highest grade of anti-corrosion materials are used in the manufacture of the spindle, bearing and mouth ring, which combined with leak-free seal-less structures, ensure the safe and durable transfer of strong acids and strong alkaline liquids. For most of the applications, Polypropylene (PP) is sufficient.

If concentrated chemicals must be pumped and/or at higher temperatures, the medium contact materials
consists of PVDF. The plastic parts are reinforced with fibres. As a result, the pump is stronger despite the fact that less material is used, and retains its physical characteristics in the case of possible increases in temperature and/or pressure.In this way, the chance off leaking gaskets is minimized.

Impeller
AM pumps are equipped with a closed impeller (except the smallest type that has an open impeller),
with optimum efficiency. It is fixed onto the shaft independent from the direction of rotation.
For all transport or circulation duties of pure chemicals or other corrosive liquids.
