LOWARA SVI PUMP -22mm Pump OEM Equivalent Seal

This seal is a balanced, wave-spring component mechanical seal with a drive-pin collar and stationary cup/O-ring seat, specifically configured as a 22 mm replacement seal for Lowara SV & e-SV series pumps.

Lowara SV Series 22mm Mechanical Seal (SV 10, 15, 22 Replacement)

Product Summary: Direct-replacement 22 mm balanced mechanical seal designed for Lowara® SV and e-SV vertical multistage pump models (including SV10, SV15, and SV22). Engineered with a rugged stainless steel cage, compact wave-spring design, and positive drive pins, this unit handles high-pressure cycling, thermal expansion, and moderate solids without seal face distortion or spring fouling.

Key Technical Features

• Balanced Wave-Spring Architecture: The multi-window stainless steel sleeve houses a heavy-duty wave spring that distributes face load uniformly across 360∘360∘, maintaining seal face parallel alignment even under high differential head pressure.

• Positive Drive-Pin Retention: Features integrated drive pins on the collar backplate to ensure positive torque transmission from the pump shaft without slipping or fretting the shaft sleeve.

• Anti-Clog Flush Ports: The precision-machined peripheral window ports allow maximum pumpage flow directly over the spring and inner face, continuously flushing away silt, debris, and heat buildup.

• Matched Stationary Seat: Paired with an elastomeric L-cup / O-ring mounted stationary seat for secure, leak-tight installation inside the pump's seal chamber recess.
