Liquid ring vacuum pumps type 2EB
2BE series water ring vacuum pumps and compressors are high-efficiency, energy-saving devices that are typically used for pumping gases that are free of solids, insoluble in water, and non-corrosive. This allows vacuum and pressure to be created inside sealed containers. Thanks to modifications of the construction materials, they can also be used for pumping corrosive gases or using corrosive liquids as the working fluid. Critical components such as the pump shaft, impeller and distributor plate have been optimized to solve dynamic balancing problems. The impeller and pump shaft are press fit with clearance, which ensures reliable operation and smooth running.

Product overview
2BE series water ring vacuum pumps and compressors are high-efficiency, energy-saving devices that are typically used for pumping gases that are free of solids, insoluble in water, and non-corrosive. This allows vacuum and pressure to be created inside sealed containers. Thanks to modifications of the construction materials, they can also be used for pumping corrosive gases or using corrosive liquids as the working fluid. Critical components such as the pump shaft, impeller and distributor plate have been optimized to solve dynamic balancing problems. The impeller and pump shaft are press fit with clearance, which ensures reliable operation and smooth running. After welding the impeller, the entire assembly is subjected to complex heat treatment. This gives the blades excellent strength, which ensures they are resistant to impact and bending. As a result, they can withstand harsh operating conditions associated with shock wave loading.
Product Features
Single-stage direct-acting design that is simple, easy to maintain, reliable and highly energy efficient. Withstands harsh operating conditions including high discharge volume and shock wave loads.
Equipped with a built-in air separator, multiple inlets and outlets, and an inspection window with an outlet valve on the pump cover. The clearance between the impeller and the distributor plate is adjustable using thrust bearing end caps, making it easy to install, use and operate.
Scope of application
Widely used in pulp and paper, chemical, petrochemical, light industry, pharmaceuticals, food processing, building materials, electrical engineering, coal beneficiation, mineral processing and fertilizer production.
Particularly effective in the coal industry for the recovery of highly flammable and explosive gases such as coal bed methane and methane. Can be configured with ground methane recovery stations and integrated with mobile methane recovery systems.

Constant water pressure variable frequency control equipment is a new mechatronic water supply equipment that combines frequency variable speed control technology and programmable control in automatic pump control devices, integrating them with a group of motors and pumps.
YZSP Diesel Self-Priming Pumps
YZSP Series Diesel Engine Self-Priming Pump is an innovative design of high-performance diesel-powered self-priming pumps that are not prone to clogging. Installation only requires the pump to be placed next to the sump and the suction piping must be below the liquid level to operate. The wide, non-clogging impeller design allows solids up to 76mm to pass through, and the retractable design facilitates quick maintenance and repair using standard tools. The SP Series Diesel Sprinkler Pump is recognized worldwide as the “King of Self-Priming Sewage Pumps.”
Horizontal multistage centrifugal pumps (light series) CHL and CHLF
CHLFs are equipped with a maintenance-free mechanical seal. The pump flow parts are made of stainless steel (304 or 316), and various materials of carbide seals guarantee the absence of leaks when pumping various media; Low noise level: The pump operates smoothly on two low-noise bearings and, with the exception of a weak motor sound, is almost silent.
Mechanical diaphragm dosing pumps DJ-Z
The DJ-Z mechanically driven diaphragm metering pump operates on the principle of a turbine driven worm gear, which drives a mechanical diaphragm. This design is suitable for dosing liquids in low pressure systems. The diaphragm metering pump provides complete isolation between the fluid in the flow and the diaphragm lubrication mechanism of the drive. With its advanced design, it provides infinitely variable flow control from 0-100% to meet various process requirements. It provides precise dosing of corrosive and non-corrosive fluids free of solids.
YZZW Diesel self-priming pumps
The YZZW diesel engine self-priming pump combines self-priming capabilities with a hassle-free drainage system. Thanks to axial recirculation and external mixing with a wide flow channel of the impeller, it does not require the installation of a foot valve and can pump liquids containing large solids or long fibrous impurities.
Petrochemical Process Pumps API 610 YZA
The YZA series of petrochemical process pumps are designed to API 610 standards and feature a centrally supported OH2 ZE pump housing design. Both series use single-stage radial impellers with axial suction and radial discharge. Hydraulic balancing is achieved through front and rear wear rings and balancing holes tailored to the operating conditions.
Vertical magnetic pumps CQB-L
CQB-L Magnetic Drive Vertical Chemical Pump, which is a magnetic coupling centrifugal pump, is a new type of pipeline pump developed by our company based on more than ten years of experience in designing and manufacturing horizontal magnetic pumps. It combines the characteristics of an ISG centrifugal pipeline pump with the advantages of magnetic chemical pumps to ensure leak-free pipeline operation.
DBY Non-Metallic Electric Diaphragm Pumps
DBY non-metallic electric diaphragm pump is made of PP engineering plastic and PVDF fluoroplastic, suitable for corrosive liquids, acids, alkalis, solvents, toluene, pharmaceuticals, food, cosmetics and similar applications. The DBY series electric diaphragm pumps use cycloidal gear reducers to transmit motion. The crankshaft and slider mechanism drives a double diaphragm that reciprocates, resulting in alternating changes in the volume of the working chamber and ensuring continuous inlet and outlet of fluid.
