Product Details
Grundfos Pump Seal Grundfos JMK Seal
The Grundfos JMK seal is a cartridge mechanical seal specifically
designed for Grundfos pumps, such as the CR and CRN series. Its
characteristics are as follows:
- Performance Parameters: It can operate at a speed of up to 20 m/s, within a temperature
range from -30°C to +180°C, and withstand a maximum pressure of 40
bar, enabling it to adapt to a variety of working conditions.
- Structural Design: It features a cartridge structure, which simplifies installation
and maintenance. There is no need to measure the sealing working
length. During installation, simply sleeve it on and tighten the
bolts of the sealing cover to ensure the assembly quality and avoid
leakage issues during startup.
- Sealing Materials: The sealing face materials are typically silicon carbide,
tungsten carbide, etc., possessing high hardness, wear resistance,
and corrosion resistance. The secondary seal often uses fluorine
rubber, ethylene propylene diene monomer (EPDM) rubber, etc., which
can adapt to different working media and temperature conditions.
- Quality Assurance: The production process strictly adheres to quality control
standards. From raw material procurement to finished product
inspection, each stage is closely monitored to ensure reliable
product quality, stable performance, and a long service life. It
usually comes with a warranty period of up to 12 months.
