Product overview
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. Shaft sealing is accomplished using stuffing box packing, single mechanical seals or double single mechanical seals with the option of cooling, flushing or sealing fluid systems. Standard piping is designed to API 610 specifications. Inlet and outlet flanges have the same pressure rating. When viewed from the motor drive side, the pump rotates clockwise.
Product Features
Insulating housings are available.
Easy maintenance, requiring only disassembly of the coupling gasket.
Wider performance range compared to traditional centrifugal pumps.
The pump design has been improved in accordance with API 610.
Temperature range: -80°C to 450°C
Extended shaft seal and bearing life with low vibration and noise levels
Dry shaft design without liquid ingress
High working pressure: YZE pumps up to 5.0 MPa
Rear vanes or counterbalance holes with impeller to reduce axial thrust and seal chamber pressure
Scope of application

Metal electric diaphragm pumps DBY
DBY metal electric diaphragm pumps are available in cast iron, aluminum alloy, PTFE coated and stainless steel. The DBY series electric diaphragm pumps use cycloidal gear reducers to transmit motion. Using a crankshaft and slider mechanism, they drive a double diaphragm that reciprocates, resulting in alternating changes in the volume of the working chamber and ensuring continuous inlet and outlet of fluid.
CQB Stainless Steel Magnetic Pumps
The CQB stainless steel magnetic pump is designed in accordance with the HG/T 2730 standard. It uses modern magnetic principles, namely the magnetic force of permanent magnets for contactless torque transmission.
Sanitary screw pumps type GF
The GF stainless steel sanitary screw pump operates on the principle of counter-rotation of interacting elements with positive displacement. Designed to transport demanding food or pharmaceutical media, its main operating components include an eccentric screw (rotor) and a fixed bushing (stator). The unique geometric configuration of these two components creates separate, sealed chambers.
ISW and ISWH Single Stage Horizontal Pipeline Centrifugal Pumps
ISW/ISWR/ISWB/IHW/IHWB horizontal centrifugal pumps are highly efficient and energy-saving products designed based on the unique combined design of IS type centrifugal pumps and vertical pumps. They have been optimized using domestic advanced hydraulic models, and based on their structure, a combination design with conventional horizontal pipeline centrifugal pumps has been developed.
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.”
Vertical pumps for installation inside/outside tanks YZCN and YZCW
The YZCN vertical acid-alkali resistant pump with internal reservoir features an exceptionally wide range of applications.
