Qixing is a professional M74D Multi Spring Mechanical Seal manufacturer and supplier offering customized factory solutions for industrial buyers. This double mechanical seal uses an O-ring design, covers 18-100 mm shaft sizes, and supports water, sewage, oil and other moderately corrosive fluids.

The Qixing M74 Multi Spring Mechanical Seal fits almost any European pump cavity. Rated to +190C and 1.2 MPa in shaft sizes 14 mm to 100 mm, it is the multi spring mechanical seal to specify when seat-cavity flexibility and high-temperature service matter more than maximum pressure. Buy direct from the Qixing factory in China.

The Qixing 891 Multi Spring Mechanical Seal is a heavy-duty multi spring mechanical seal rated to 2.5 MPa, -20C to +180C, in both metric (25-100 mm) and imperial (1.000"-4.000") shaft sizes. Purchase wholesale or OEM at affordable price. Send inquiry now!

The 8D single spring mechanical seal is the positive-drive version of the Qixing 8. It shares the same O-ring single spring design and the same +200C, 20 m/s, 1.2 MPa envelope, but adds a positive drive element (the d1 drive pin) so the rotary face cannot slip on the shaft under high torque. Shaft sizes 10 mm to 80 mm. Send inquiry now!

The 8 single spring mechanical seal is Qixing's high-temperature O-ring single spring seal: rated to +200C and 20 m/s, with an O-ring secondary seal in place of a rubber bellows. Shaft sizes run 10 mm to 80 mm, pressure to 1.2 MPa. It suits clean water, sewage, oil and moderately corrosive fluids that run hot or fast. Buy the 8 single spring mechanical seal direct from the Qixing factory in China at OEM and wholesale pricing.

The 7D single spring mechanical seal is built for heat and speed. With an O-ring pusher design rated to +200C and 18 m/s, it runs where standard single spring seals fade - hot water, thermal media, and high-speed two-pole motor pumps. Shaft sizes 10 mm to 100 mm, pressure to 0.8 MPa. Contact us for quotation!
