SAFEMATIC SWE-GLS Professional Equipment for Industrial Flow and Pressure Supervision

The SWE-GLS is a seal-water supply and monitoring unit for mechanical seals. It feeds conditioned cooling or sealing water to the seal and keeps watch on that water so the seal is not run dry: when the seal-water flow or supply pressure drops below the set value, the unit raises an alarm (and can trip or signal) so the pump can be stopped before the seal is damaged. We supply compatible replacement units and spare modules built to the SWE-GLS configuration, for use where the original equipment needs to be serviced or replicated.

The same SWE-GLS product is offered in two port configurations — single-port for one mechanical seal and double-port for two mechanical seals — so one page covers both; the port version is selected to match the seal arrangement on site.

Brand note: SAFEMATIC is referenced here for identification and compatibility purposes only. We are not affiliated with, authorised by, or endorsed by the original manufacturer.

Both versions share the same tank or pot, control unit, solenoid valve, level switch and filter; only the number of seal-water connections and flow/pressure instruments differs. Port configuration is confirmed at order against the seal type and connection size.

From seal duty to a working seal-water system — A replacement seal-water control and monitoring unit is typically built and checked through the following steps:

1. Confirm the seal duty — collect the seal type, the cooling-water requirement (flow, pressure, quality), the port configuration (single or double), and the connection size and standard.
2. Configure the SWE — select the seal-water tank or pot, the control unit, and the flow and pressure instruments suited to that duty and port count.
3. Assemble — build the skid or panel, then make up the piping and wiring to the seal(s) and the supply.
4. Set & calibrate — set the low-flow and low-pressure alarm thresholds and calibrate the instruments against a reference.
5. Test — simulate loss of seal water and confirm the alarm and the output (signal / trip) act as intended on each monitored port.
6. Inspect & pack — carry out a visual and calibration check, then pack for shipment.

Introducing the brand we created to provide professional overall technical solutions in fluid machinery and engineering. Industrial control and drive equipment, mechanical seals, overseas field engineering solutions, etc.

We have a series of professional technologies and product brands that can provide you with leading technical services, sales support and product supporting solutions - empowering you with pumps, frequency converters, servo drives, PLC servo drives HMI, industrial control cabinets, motors, Reduced motors, mechanical seals and systems, couplings, gearboxes and engineering solutions (overseas on-site service of 3D scanning reverse molding of pump replacement parts to your satisfaction, and on-site equipment debugging services by overseas dispatched engineers).

For a seal-water system, packing is arranged by size and order volume:

• Panel / small module — individually wrapped and packed into a paper carton with cushioning.
• Skid or larger assembly — protected and packed in a wooden crate suitable for sea freight to avoid damage in transit.
• Custom packing — we can follow a customer's specified packing requirement.

Transport mode is chosen by weight and required lead time: express, sea freight, air shipping, land transport, or post.
