TXL Compact Jaw Coupling, for Small-to-Medium Fluid Pumps and Refrigeration Units

The TXL series taper-bush jaw coupling is designed for European-standard small-to-medium fluid pumps, industrial oil pumps, and refrigeration compressor units. Its defining feature is an extremely axially compact structure combined with taper-bush locking, which perfectly solves the long-standing pain point of traditional pump couplings being very troublesome to service.

Item Specification
Model TXL series (such as TXL 100 / 150 / 200)
Body material 45# steel / high-strength aluminum alloy (steel is normally used for European-standard pumps)
Surface treatment Natural-finish rust protection / black oxide treatment
Structure type Tapered bore (taper-bush type), compact jaw elastomer connection
Elastomer material High-temperature-resistant NBR rubber / polyurethane (PU)
Installation Taper-bush locking, axially compact, installation and removal without moving the pump
Applicable standards DIN standards / general European pump-industry specifications
Compensation capability Compensates small radial and angular misalignment; easy axial plug-in and removal

1. Axially compact, a perfect fit for the pump-to-motor gap: For the very limited installation space between pump and motor, the TXL series uses a short-pitch compact design that greatly reduces overall length. This tightly coupled structure makes the equipment assembly smaller and reduces its footprint.
2. Taper-bush locking, a "no-move-the-machine" tool for pump maintenance: With traditional pump elastomer couplings, replacing the elastomer or servicing the mechanical seal often means prying a heavy motor out of position. With the TXL taper-bush structure, just loosen the bush bolts to slide out half the coupling easily, leaving ample service space without moving the motor or pump.
3. Stepped pre-tightening, protecting precision pump bearings: Paired with a high-quality NBR or PU elastomer, it not only transmits torque but also effectively absorbs the high-frequency vibration of small-to-medium motors, preventing vibration from reaching the pump and damaging the mechanical seal, greatly extending pump life.
4. High-precision European-standard manufacturing: The body is precision-machined from 45# steel with a black oxide or rust-proof finish, giving better corrosion resistance than ordinary cast iron. Its very high dynamic balance accuracy keeps it smooth and quiet even in high-speed pump applications at 3600 rpm.

A "dedicated solution" for the pump and valve industry: Small, no need to pry the motor, and highly concentric, it is the best upgrade over traditional straight-bore pump couplings.
Globally universal European-standard spare part: Fully conforms to European DIN standard mounting distances and taper-bush bores, a direct replacement for overseas pump equipment.

Fluid pump industry (core scenario): Centrifugal water pumps, chemical process pumps, fire pumps, and gear oil pumps.
HVAC and refrigeration: Central air-conditioning circulation pumps and chiller compressors.
Light industry and environmental protection: Wastewater treatment equipment, fan drives, and small industrial compressors.
