HTM SS – Magnetic drive centrifugal pumps in stainless steel AISI 316

HTM SS316 pumps are magnetic drive centrifugal pumps made of metallic material (stainless steel AISI316) suitable to transfer hydrocarbons, solvents, refrigerants and many other dangerous liquids. These pumps have been designed with a sealless design where the pump is closed coupled to the motor and the motion occurs through magnetic joints. The external magnet, in fact, is mounted on the drive shaft and it transmits the motion from the motor to the internal magnet connected to the pump impeller which rotates and moves the fluid through the pump. It is the magnetic attraction between the external magnet and the internal magnet which allows the full torque of the motor to be passed to the impeller. The two magnets are separated by a rear casing that creates a hermetic containment of the liquid which has no access to the outside, thereby preventing any leakage of fluid or other fugitive dangerous emissions. Magnetic pumps require minimum maintenance with consequent save in terms of repairing and spare parts costs. Pumps model HTM SS316 are available also for Atex zone 2 and zone 1.

Mag drive centrifugal pumps model HTM SS316 are suitable to pump hydrocarbons, solvents, refrigerants, cryogenics, heat transfer oils and dangerous liquids used mainly in chemical and petrochemical industries, pharmaceutical, biotechnology, refineries, fertilizer processing, painting industries, electronics, food processing, paper mills, metal finishing machines, PCB printed circuit boards, pesticide processing, water treatment plants, thermoregulation processing, filter units, military industries, loading/unloading of tank trucks, dairies, packaging industries and many more. These kind of pumps can easily handle acids without any problem of chemical corrosion such as for example: acetic acid, acetone, alcohol ethyl, ammonia, detergents, fuel, fuel oils, gasoline, hydraulic oil, naphtha, sulfuric acid.
