According to JB/T8688-1998, GB/T13007-91, GB/T5656-94 and Q/YSB01-2002JB/T, our products are jointly designed, developed and manufactured with Zhejiang Province Electric & Mechanical Institute, e. G. "Lequan" brand FS model, S model and SZ model engineering plastic anti-corrosive pump, which are licensed products of pumping products given by Mechanical Ministry.

Our products have reasonable structure, reliable operation, excellent anti-corrosive capability and advanced dealing capability. Pumping components are all made of outstanding engineering plastic with excellent anti-corrosive performance moulded at one time. Therefore, our products are able to run constantly in environment of media of 0~120 and resist corrosion of all kinds of strong acid, alkali and muriatic acid constantly.

The pump adopt mechanical sealing of outer installed corrugated pipe, saving the sealing cooling device and eliminating flowing, emitting, dripping and leaking, which offer outstanding and reliable tools to transport corrosive liquid media of "three wastes" treatment engineering of all chemical industrials.
