Pumps

The ANS-B series is q horizontal, radial split, single stage, single suction, overhung centrifugal pump with a foot-mounted volute casing, The impeller is designed as a fully open structure with a back blade, which is suitable for abrasive liquids containing large particles or strip fibers. The Rigid shaft design, impeller and shaft are connected by a thread with no impeller nut. The bearing component is provided with a bearing box structure and a connecting-bolts plus jacking-bolts design for the bearing housing and bearing box so that the clearance between the impeller and the casing can be easily adjusted without disassembling the pump. This ensures that the pump can run within the high efficiency range. The adjusting action is easy and reliable and the maintenance is simple. The radial bearings are deep groove ball bearings and the thrust bearings are angular contact ball bearings, which can withstand axial forces from two directions.

The EDS series is horizontal, axially split, double-suction, single stage or two stages, between-bearings, centerline-mounted or foot-mounted centrifugal pump. The double volute structure reduces the radial force effectively. The axial split structure helps rapid disassembly of the rotor and parts maintenance without disassembling the pipeline and the pipeline-related system Single-stage double-suction or two-stage double-suction + single-stage structure impeller, high cavitation resistance, high efficiency and stability. Self-balancing axial force, no complex balance disc, balance drum and other balance mechanisms. EDS series pump is a new generation of high-efficiency energy-saving products with a three-dimensional model and CFD flow field analysis, a wide range of flow, high efficiency and good cavitation resistance.

The HDD series is a horizontal, radial split, double suction, centrifugal pump with volute casing that can be configured as single or two stages. It can be centerline-mounted, with top-suction, top-discharge or side-suction, side-discharge/side-suction, top-discharge options. The spiral suction chamber provides better flow conditions, and a uniform velocity field is achieved at the impeller inlet. The double-suction impeller has improved cavitation performance, reducing installation costs and prolonging bearing life. The pump features a rigid shaft design, with a first-order critical speed that is more than 1.2 times the designed speed, ensuring smooth operation.

The SCSK Series is a horizontal, single-casing, axial-split, centerline-mounted, multistage pump with symmetrically arranged impellers. The inlet and outlet flanges are arranged on the pump casing to allow for easy detection and maintenance of the pump without having to move the suction and discharge pipelines. The impellers are arranged back-to-back in a symmetrical manner, resulting in a small residual axial force. The axial force is balanced by adjusting the size of the throttle bushing and other parts, eliminating the need for complex balancing devices. Additionally, the inner hole of each shaft sleeve is equipped with a spiral groove, and the axial dimension of the shaft sleeve is short, making it especially suitable for transferring liquids containing particles. The static friction pair is designed in a separate structure, making it more convenient and faster to replace. The rotor parts do not need to be disassembled and installed again after dynamic balance.

The SCS series is a horizontal, radial-split, multistage, ring-section pump. It features a radial diffuser-type casing structure, and can be centerline or foot-mounted based on the operating temperature. The flexible arrangements of the suction and discharge ports allow for various installation options. This series is characterized by its simple and reliable structure, high stability, long service life, and easy maintenance. The series features arrangement impellers and double-balancing drums to balance the axial force. The flexible design in dry state and rigid design in wet state of the rotor ensures stable and reliable operation. The first-stage impeller and second-stage impeller are different designs, with the first-stage impeller having high anti-cavitation performance and the second-stage impeller offering high efficiency. The impellers are designed as sliding structures, making them easy to install and disassemble.

The DCS-K series is a double-casing, horizontal-split, horizontal, multistage centrifugal pump designed for extreme conditions such as high temperature and high pressure. It is centerline-mounted, features a heavy-duty design with good thermal stability, and can properly satisfy the nozzle load requirements specified by API610. The double-casing structure ensures high safety and reliability. The inner casing is an integral pull-out design, allowing for easy installation and simple maintenance. The impellers are arranged back-to-back without traditional balancing devices, ensuring stable and reliable operation. The first-stage impeller is designed with low cavitation. The pump can be fitted with self-lubricating bearings or forced lubricating bearings to meet different power, speed, and service requirements.

The LDB series is a vertical, double-casing, radial-split, radial diffuser or bowl type, multistage centrifugal pump. It features a welding structure for the inlet and outlet section and barrel bag void defects. The first-stage impeller and second-stage impeller have different designs, with the first-stage impeller being based on high cavitation resistance and the second-stage impeller designed for pump efficiency. The impellers can be designed with a diffuser to reduce insertion depth under cavitation-demanding conditions. The pump uses either a balancing drum (LDB-B) or disk (LDB-A) design to balance the axial force. The flexible shaft is multi-point supported and the distance between supporting points conforms to API610 standard. The pump is equipped with ZL series bearing group, which is grease lubricated and has residual axial force balanced by a pair of angular contact ball bearings.

The High-pressure submersible pump is a vertical, multistage, radial-split, diffuser structure centrifugal pump installed outside the storage tank. The pump head is installed inside the suction cylinder, which is installed as a pit-type. The flow passage component and motor have a coaxial design, with the pump being submerged in the medium. The pump uses a minor radius balance disk and drum combination design to balance the axial force. It has a 3-point rolling bearing support with auxiliary support provided between stages to improve stability. Without dynamic sealing, the only leakage point is the leakage of the medium in the pump well along the cable, resulting in zero leakage, cooling by the pumping medium, explosion-proof requirements and reliability. The pump is equipped with a vibration, liquid level, temperature, and pressure monitoring system to ensure the safety of the pump operation.
