TYPE 700

The Sealergy Seals Type 70 is a stationary-mounted highly compact elastomer bellows design, highly suitable for high-shaft speed water pump applications. The design features a boot-mounted rotary counter ring that is intended to be inserted into a recess in the equipment impeller, with the metal sprung unit pressed into the static pump housing. The shaft clearance on both sealing faces enables one size to be used on a number of shaft sizes. No part of this design contacts the pump shaft so is therefore bi-directional, and the spring is static and removed from centrifugal influences allowing very high rotational speeds to be sealed. Supplied with a Sealergy Seals Type 70 boot-mounted stationary highly suited to low-pressure light water circulation duties. This is a multi-spring, high-pressure seal with O-rings or PTFE V-packings as secondary seals. It is a bi-directional pusher-type mechanical seal, making it suitable for a variety of elastomers. The design is available in both an unbalanced version for low-pressure applications and a balanced version for high-pressure applications. It can be configured as a double seal for handling toxic or hazardous liquids. It is commonly used for a wide range of clear, non-abrasive liquids in many types of equipment.
