Frequently Asked Questions

What is the difference between SQS65 and KWS65 inlet caps on the siamese?

They follow different international coupling standards for fire engines. SQS65 matches the international fire-service pattern and KWS65 the German pattern — specify the standard used by your fire department so the inlets are directly compatible with its appliances.

Can two fire engines supply the SQD100 at the same time?

Yes. The twin DN65 inlets allow simultaneous connection of two fire engines, combining their flow into the single DN100 flanged outlet for high-capacity pump supply.

Does the SQD100 include a flow control valve?

Yes — an integrated control valve with handwheel is built into the powder-coated ductile iron body for flow regulation, with braided steel safety cables on the caps to prevent loss during operation.

What is the pressure rating and size of the SQD100-1.6?

Rated 1.6 MPa in a compact 120 mm body — suitable for airport, industrial yard and municipal fire protection pump connections where space is limited.
