Rokee® Customized Shim Pack Coupling For Pumps for Customers, Rokee® is a well-known high-quality supplier of couplings and technical services in China.
The pump shim pack coupling adopts a multi-layer stainless steel thin plate (0.2-0.5mm) laminated design, and is connected to the shaft system through high-strength bolt groups. For the special requirements of pump equipment, the selection should focus on:
Torque matching: Calculate the operating condition coefficient K=1.5-2.5 (upper limit for chemical pumps)
Corrosion resistance level: 316L stainless steel membrane suitable for pH 1-14 medium environment
Axial compensation capability: Must meet ± 1.5mm thermal expansion displacement (typical value for chemical pumps)
Speed limit: The standard model allows a speed of 4000-8000rpm, while the high-speed model can reach 15000rpm
Typical models include:
JMJ Double Diaphragm Type: Compensating for Composite Displacement, Suitable for Long Axis Distance Heart Pumps
DJM expansion sleeve type: keyless connection, convenient maintenance (preferred for chemical pumps)
SJM stainless steel type: made of 316L material as a whole, resistant to acid and alkali corrosion
