Magnetic drive pumps often made of stainless steel or plastic, mainly used in the chemical industry. For the transfer corrosive acid and alkali liquids.Before you buy the pump.Please read the following information.This information will help you to use magnetic pump.

Stainless steel magnetic drive pumps
In the fields of petroleum,chemicals,war industry and pharmaceuticals etc. There are often needs to handle some corrosivity liquids.For this reason, we dedicate ourselves to devlopment fully sealed,leak-tight and corrosion-resisting centrifugal pumps.Magnetism-driven silent seal technology performs leak-tight seal in pump industry.
Stainless steel magnetic drive centrifugal pump is a late model uses the theory of modern magnetics.The noncontact transfer of torque is actualized by the magnetic force of permanent magnet.
Namely,when motor drives outer rotor(outer magnet steel) assembly rotating,inner rotor(inner magnet steel) assembly will rotate synchronously.With innpeller driven by magnetic line of force through spacer sleve under the function of magnetic field. As medium is closed in the actionless spacer sleeve. And away from the trouble of leakage at shaft seal borne by mechanical drive pumps.
Stainless steel magnetic pumps are widely used in the industries of petroleum,chemicals.To handle corrosive liquid not containing scrap irons,especially volatile,toxic and precious liquids.
Plastic magnetic drive pumps installation and operation
- 1:Magnetic pump should be horizontally installed,but not upright. Plastic centrifugal pump is not able to endure the weight of pipeline. In case of special occasions requiring upright installation,motor should be kept upward.
- 2:When liquid level is higher than the centerline of pump,turn on valve of intake pipe before start.When liquid level is lover than the centerline,a bottom valve should be fitted to the pipeline.
- 3:Check before operation: Make sure that motor rotates flexibly without jamming and abnormal sound. And that all fasteners are not loosened.
- 4:Check whether motor rotates in accordance with the direction sign.
- 5:After motor is started,slowly turn on discharge valve. When pump enters normal working state,adjust the discharge valve to the required opening.
- 6:Before pump stops working,turn off discharge valve first,and then the value of intake pipe.
Engineering plastic magnetic drive pump temperature should be＜60℃. Inlet pressure not greater than 0.1Mpa. Maximum working pressure at 0.6MPA;Stainless steel magnetic drive pump temperature should be ＜100℃. Inlet pressure not greater than 0.2MPA,maximum working pressure at 1.6MPA.
Cautions for magnetic pumps
- 1:As the cooling and lubrication of magnetic pump’s bearing depends on the medium to be handled.That’s why unloaded operation is absolutely prohibited.Meanwhile,pay close attention to avoid the unloaded operation after re-start due bto power cut in process.
- 2:If the mediums to be handled contain solid particles,then there should be a filter net at the entrance of pump.If there are ferom agnetic particles contatined in mediums,a magnetic filter should be fitted(available in factory for your options).
- 3:The mediums to be handled,as well as their temperature. Should be kept within the allowed scope of pump material(please consult with relative technical ddepartment).
- 4:For mediums easily deposited or crystallized: Please flush immediately after use to clear away the deposited liquid inside.
- 5:In case of any abnormal conditions(like large noise or violent vibration) occurred after long-time operation or during operation.Disassemble the bearing and end-face rotating ring for examination of abrasion. If the clearance between bearing and axle sleeve is greater than 0.5~1mm. Axial drunken-ness of impeller from 2~3mm,then the bearing and axial rotating ring shoul be replaced.
