 ISP SB1 O ring pusher seal

ISP SB1 O ring pusher seal is the well replacement of John crane type SB1 seal.


The Safeseal Type SB1 is a single-cartridge seal for use with clean fluids and lubricants. It is
versatile and easy to install and maintain. Although the design of the seal is simple, it contains
advanced technical features, such as patented seal face holders and elastic mating ring. Seal 
faces are installed using a patented heat shrink process ensuring correct, distortion-free face 
alignment at all recommended temperatures. The Type SB1 seal is applicable for a wide range 
of duties such as water, oil, solvents and pulp. 
Several variant of the design available for different services:

Type SB1 — Single, balanced cartridge seal, metric units (DIN) 
Type SB1A — Single, balanced cartridge seal, imperial units (ANSI)

Type SB1B — Single, balanced cartridge seal, imperial units for big box bore pumps. The Type 
SB1B flange is designed to fit bigger stuffing box diameters.

Type SB1S — Single, balanced cartridge seal, imperial or metric units. Metric versions of SB1A 
seals are also called SB1S.

Features

The springs are located in the stationary body of the seal, reducing risk of the springs becoming
clogged.

PTFE slot rings replace the traditional O-rings in places where they are exposed to the product, 
preventing sticking.
Protected faces, the seal face carriers are driven by machined fits, preventing metal stress from 
distorting the face.
