Custom seals for water pumps and flushing systems 

Application: Pumps and valves for water and wastewater flow

Seals play a crucial role in valves and pumps ensuring that water is available when and where needed, at the same time guaranteeing that no leakage occurs or excess water is wasted.

Requirements

• Parts fit existing equipment/standard specification requirements
• Excellent chlorine resistance
• Meet multiple global standards
• Long life
• Cost-effective performance

Solution

Rotary Seals, Diaphragms, Custom Molded Parts

Our engineers work with our customers to design, test and identify a sealing solution which meets expectations, thereby minimizing downtime and improving maintenance cycles.

Custom sealing solutions for your application 

Application: Water fixtures

Within a faucet or showerhead, there are several sealing components. Seals are used to regulate the flow of water, to mix hot and cold waters and also to control the flow of water coming out.

Requirements:

• High reliability
• High-precision components
• Compliance with country specific potable water standards e.g. FDA, , NSF, KTW, WRAS, ACS

Solution

Depending on your specific application needs, Trelleborg Sealing Solutions offers a range of products:

• O-Rings
• LSR Custom molded parts: our flashless molding capabilities ensure a high level of quality and consistency
• Two-component parts: designed with the customer, two-component parts are leak-proof as they are fully bonded and ease the assembly, production and service processes
• Customer-specific solutions

Optimum fit and long service life are crucial
