59U Multi Spring Pump Seal
Product Description
The 59U Multi Spring Pump Seal is a mechanical seal designed for
centrifugal and rotary pump applications. It features a multiple
spring configuration, which ensures uniform axial pressure
distribution and stable performance under varying operational
conditions, including shaft runout and vibration. This design
facilitates consistent sealing face contact and enhanced heat
dissipation. The seal is engineered to handle a range of media,
including water, process fluids, and mild abrasives, within its
specified pressure and temperature ratings. Typical construction
materials include corrosion-resistant components such as silicon
carbide or tungsten carbide for the faces and elastomers like FKM
or EPDM for secondary sealing. It is suitable for standard
industrial pumping equipment in chemical, petrochemical, and
general industrial services.

Frequently Asked Questions
Q1: What is the primary design advantage of the 59U Multi Spring
Pump Seal?
A1: Its multiple spring design provides more consistent closing
force and better tolerance to shaft misalignment and vibration
compared to single-spring seals.
Q2: In which types of pumps is the 59U Multi Spring Pump Seal
commonly applied?
A2: It is commonly applied in ANSI standard chemical process pumps,
API 682 seal chambers, and other general-purpose centrifugal pumps
across various industries.
Q3: What are the standard face material options available for the
59U Multi Spring Pump Seal?
A3: Standard options often include Tungsten Carbide vs. Silicon
Carbide and Silicon Carbide vs. Silicon Carbide, selected based on
the specific fluid and operating conditions.
Q4: How does the 59U Multi Spring Pump Seal perform in abrasive
service?
A4: With appropriate hard face material pairs like Silicon Carbide
vs. Silicon Carbide, the 59U seal can handle mild abrasive
slurries, though external flush plans may be recommended for severe
applications.
Q5: Is the 59U Multi Spring Pump Seal suitable for high-temperature
applications?
A5: Yes, when equipped with high-temperature elastomers or metal
bellows and appropriate face materials, it can operate within
elevated temperature ranges, subject to specific model
configurations.
Q6: Can the 59U Multi Spring Pump Seal be configured for double
seal arrangements?
A6: Yes, the 59U seal cartridge can be engineered as a double (or
dual) pressurised seal for handling volatile, hazardous, or
zero-emission services.
