Its performance parameters are similar to those of WLLENPVMPS in the Federal Republic of Germany and MARIOWPUMPS in the United States. It is suitable for a series of supporting products such as filter press feeding systems and filling equipment. The products have been widely used in various fields such as petroleum, chemical industry, electric power, food, medicine, papermaking, metallurgy, energy, buildings, municipal engineering, sewage treatment, environmental protection, water supply and drainage, etc., and are deeply loved by users.

No need to fill water, strong self-priming ability. Directly separate the transported medium and the transmission mechanical parts, so the medium will never leak out. And the pump itself has no shaft liquid seal, which greatly extends the service life. Application areas: Diaphragm pumps have an absolute dominant position in the painting and ceramic industries; they are expanding their market share in environmental protection, wastewater treatment, construction, sewage, and fine chemicals, and have an irreplaceable position in other pumps.

It is designed in accordance with coal mine standards and coal mine environment. It adopts, absorbs and improves advanced pneumatic diaphragm pump production processes and core technologies. It is a revolution in traditional mining water pumps. It is suitable for drainage work in almost all forms of mining, including underground, open-pit, dredging and on-site mining processes for coal, soft/hard rock, precious metals (such as nickel, copper, gold, silver), phosphates and diamonds. It is assessed by the State Administration of Work Safety and issued a coal safety certificate.

 Oil-free lubrication, 100% no deadlock. The unique hard seal design of the air valve (external maintenance air valve system) can be repaired from the outside of the pump body, reducing downtime and improving efficiency. Ensure that the air volume and energy consumption are minimized, and the compressed air leakage is extremely low. There is no phenomenon of poor start-up and air valve freezing and pause like other brands of pneumatic diaphragm pumps. Excellent overall sealing, the fastening design of the liquid-contacting parts of all models of SZB pneumatic diaphragm pumps adopts bolt and nut connection to ensure long-term operation without leakage.

The whole body is made of polished mirror stainless steel, with excellent hygienic performance, the clamp design is easy to disassemble and assemble, the inner wall is smooth and easy to flow, the whole pump has no dead corners and no residue, and is easy to flush, meeting customers' food hygiene requirements.

Can pump dusty materials, cement powder, lime powder, etc. High efficiency and no clogging.

Similar to the performance parameters of Ingersoll Rand ARO in the United States.
The pump body is made of cast iron, aluminum alloy, stainless steel 304, 316, 316L, the flow area is lined with fluorine and engineering plastics, and the diaphragm is made of nitrile rubber, chloroprene rubber, fluororubber, polytetrafluoroethylene (4F), polytetrafluoroethylene (F46) to meet the needs of different customers. The products have been widely used in various fields such as petroleum, chemical industry, electricity, food, medicine, papermaking, metallurgy, energy, building, municipal engineering, sewage treatment, environmental protection, water supply and drainage.
