Three-Phase Asynchronous Motor

Three-phase asynchronous motors are general-purpose industrial power unit. They use three-phase AC to generate a rotating magnetic field that drives the rotor. With a simple, robust construction and reliable operation, they are widely used to drive air compressors, pumps, fans, and various kinds of mechanical equipment.

Double-End Mechanical Seal

Double mechanical seals are widely used on reactors and agitators. With two sets of seal faces, they rely on an isolation-fluid system to provide dynamic sealing at the shaft end. They suit flammable, explosive, toxic, volatile, high-vacuum, or other duties where medium leakage and air ingress are not permitted.

Single-End Mechanical Seal

A single mechanical seal is a dynamic shaft-end seal for centrifugal pumps. Relying on one set of seal faces, it prevents the pump medium from leaking outward along the shaft. It is mainly used where there is no highly toxic, flammable, or explosive medium; its simple construction requires few support systems.

Fluoroplastic Pump Impeller 50FSB-30L

The fluoroplastic pump impeller is the core rotating component of the fluoroplastic (PTFE-lined) centrifugal pump. With a metal insert over-molded in F46/PTFE fluoroplastic, it conveys highly corrosive media such as acids, alkalis, and salts, converting mechanical energy into medium pressure and kinetic energy to achieve transport.

Fluoroplastic Pump Rear Cover 50FSB-30L

The pump rear cover (pump cover) is a key pressure-retaining, wetted component of the fluoroplastic centrifugal pump. With a metal substrate lined/encapsulated in F46/PTFE alloy, it sits between the pump body and the bracket, mounts and fixes the mechanical seal, and isolates the corrosive medium from the drive end.

Pump O-Rings

O-rings are static and dynamic seal consumables for pumps, widely used at pump covers, impeller nuts, mechanical seals, flanges, and similar locations to prevent medium leakage or air ingress.

Pump Casing Gasket

The pump casing gasket is a static sealing element between the pump body and the pump cover. Clamped at the pump-casing flange face, it prevents the conveyed medium from leaking outward at the casing joint and stops air from entering the pump body during negative-pressure operation.

Pump flange coupling

Flange couplings are mainly used to connect the drive shafts between pumps and motors, transmit torque, compensate for minor misalignment, and achieve coaxial transmission of the pump unit. They consist of two flanged half-couplings and connecting bolts, and have a simple structure and high load-bearing capacity.

Pump sleeve coupling

Sleeve couplings are rigid couplings that rely on the fit between the sleeve and two shafts to transmit torque via keys or set screws. They are compact and small in size, and are used for connecting the pump shaft and motor shaft (or internal shaft sections).

Pump Clamp Coupling

Clamp couplings are rigid clamp-type couplings that rely on friction generated by the two halves of the clamp clamping the outer circumference of the shaft to transmit torque. Disassembly and assembly require no movement of the pump or motor, and no axial movement of the shaft, making them convenient. However, they lack elastic elements, have no cushioning or shock absorption, and offer almost no compensation for misalignment.

Pump flexible sleeve pin coupling

Elastic sleeve pin couplings are a type of flexible coupling. They rely on rubber elastic sleeves for buffering and vibration reduction, and can compensate for small radial, axial, and angular misalignments. They are the most widely used couplings in centrifugal pump units.

Pump flexible pin coupling

Flexible pin couplings are a type of flexible coupling that relies on nylon pins to transmit torque. They have buffering and vibration reduction capabilities and can compensate for minor axial, radial, and angular misalignments between two shafts. They have a simple structure and are easy to maintain.

Mechanical seal

Mechanical seal, used to seal during the operation of a centrifugal pump

Pump casing

The pump casing is the core pressure-bearing and energy conversion component of the fluid delivery pump. It completely covers the impeller and other core flow components, directly determining the operating efficiency, pressure-bearing capacity and service life of the pump. It is the key basic part of various fluid delivery equipment in the mechanical manufacturing industry.

Bearing

The core transmission bearing component in the mechanical manufacturing field is often used as the core parts such as motor shaft and pump shaft.

Centrifugal Pump Impeller

It is the core energy conversion component of the fluid transfer pump, and the pump casing and pump shaft belong to the core supporting components of the pump unit.

Diaphragm

The diaphragm is the core working component of a pneumatic/electric diaphragm pump. It completely isolates the driving medium chamber (compressed air or hydraulic oil) from the conveyed material chamber. Reciprocating flexural deformation changes the volume, completing medium suction and discharge and eliminating cross-leakage between the material and the driving-side medium.

Diaphragm

Made of metal, with good sealing performance, wear resistance, and weather resistance.

Mechanical Seal (DMS)

Mechanical seals are precision, structurally complex basic mechanical components and are key parts of various pumps, reaction and synthesis vessels, turbo compressors, submersible motors, and other equipment.

Plunger Pump Check Valve

A plunger pump has check valves at both the inlet and the outlet (suction valve and discharge valve), which are core wear-prone parts; the reciprocating plunger completes suction and discharge through the alternating opening and closing of the two valve sets. Diaphragm metering pumps and high-pressure reciprocating plunger pumps both use this arrangement. A check valve is generally supplied as a set: valve seat, valve plate or valve core, spring, and valve seal ring.

Plunger Pump Plunger

It applies to reciprocating plunger pumps and high-pressure metering plunger pumps. The plunger is the core working part of the reciprocating motion, moving linearly to and fro inside the packing/sealing gland and forming a friction pair with the packing seal; it is a key wear-prone part. Diaphragm metering pumps have no plunger and rely on diaphragm transmission.

Dry Vacuum Intake Filter

Other names: Inlet dust filter and inlet filter element. Dry screw pumps have no oil mist separation, so the inlet filter is the core protective component at the front end of the pump.

Screw Pump Stator

This applies only to single screw pumps (PCP, positive displacement type)

Screw Pump Rotor

For single screw pumps (PCP) only; two-screw and three-screw pumps use metal screw rotors and have a different structural logic. The rotor is a single-helix external metal shaft that meshes with the double-helix rubber stator in planetary eccentric rotation, forming the core working pair of the pump together with the stator.

Cam Rotor Pump Cam

A cam rotor pump (also known as a cam pump or a two-lobe/three-lobe rotor pump) has a pair of rotors driven by an external timing gear to rotate synchronously in opposite directions. Under normal conditions the rotors do not touch each other, and a small clearance is maintained between the rotors and the pump casing or liner, the medium being conveyed by the change in volume. Rotors fall into two main types: integral metal rotors and rubber-coated rotors. They are the core flow-through component and an important wear-prone part.

Oil Mist Separator for Oil-Lubricated Rotary Vane Vacuum Pumps

Other names: exhaust filter, oil mist collector, and oil-gas separator; a component used exclusively on oil-lubricated rotary vane pumps.
