Water Filtration Systems

Essential for Long Bearing & Seal Life

Select or Design an Optimized Filtration Solution for Your Application

There is rarely a single “best” solution for water filtration, as every application demands different levels of water quality at the outlet and also must deal with whatever water condition is found at the inlet. Using proven standard systems and then integrating them with additional components provides the reliability and flexibility required to develop a solution that fits the need.

Standard Systems

Whenever possible, using a standard “skid” mounted system will save time, money, and reduce the complexity often associated with integrating individual components. Thordon’s standard Water Quality Package is a proven & highly reliable system, intended for bearing lubrication and cooling.

General Design Guidelines

Understand Your System
Map out a schematic diagram to understand the interaction of existing components, inlet and outlet points.
Pressure & Flow
Most bearings and seals require a minimum flow rate (moving water) AND a minimum supply pressure. Just because you have pressure does NOT mean you have flow.
Reliability is Important!
Reliability of the system is often more important than having perfectly clean water. The best filtration system is the one that can be counted on to deliver the minimum filtration level that the application requires, with minimal manual maintenance or regular intervention.
Don't Design At The Limits
It is better to have a slightly oversized system with the capacity to supply more water flow if required, rather than not quite enough. Most water lubricated bearings and shaft seals will work fine with higher water flows, but very quickly will have problems if there is insufficient cooling flow.
One Filter Can't Do It All
It is typical to use a coarse filtration stage to first remove large debris from raw water, then increase the filtration level in a second or even third stage in order to reach the level required for each downstream supply location.
Consider Additional Features
Custom systems can include redundant backup pumps, data logging, alarms, pressure switches, drain or sampling ports, special voltages or other electrical requirements, etc.
