Blackmer pump shaft seal Blackmer brand pump cartridge seal 45mm seal

Our blackmer shaft 45mm pump seal is same design as original seal,with SS316/CARBON/VITON/SS316 material.

A mechanical seal is a very effective device. Every centrifugal pump must
accommodate a spinning shaft while mechanically maintaining fluid or gas contained

in the "wet end" of the pump. Mechanical seals consists primarily of a rotary

seal face with a driving mechanism which rotates at the same speed as the pump

shaft, a stationary seal face which mates with the rotary and is retained using a

gland or in some pump models an integral stuffing box cover, a tension assembly

(utillizing springs or a metal bellows) keeps the rotary face firmly positioned

against the stationary face preventing, excluding, and containing contamination and

leakage, both when the pump is not in operation and when the pump shaft is

rotating. Static sealing gaskets, orings or elastomeric bellows are strategically

located to complete the seal assembly.

We offer quality sealing and cost-effective mechanical seal designs that help keep

equipment running longer while reducing downtime. Through our comprehensive

selection we provide mechancial seals with short lead times and with a variety of

designs for use in many common and more challenging industry applications. When

selecting a mechanical seal, it is important to know what sort of design is needed,

and we have outlined a few of the more common elements below.

In-line Seals
In-line Seals simply refers to seals that are mounted to a shaft or sleeve but are

mounted independently as individual parts.    

Single Spring Seals
Mechanical seal designs range from the work horse "single spring" mechanical seals,

to highly engineered double cartridge seals for extreme applications.

PTFE  Seals
PTFE (polytetrafluoroethylene)or as most people know it Teflon ® , has a 0-14 ph

range it usually will hold up.    Outside Seals

Outside Mechanical Seals can also be used in equipment with stuffing boxes which

will not accommodate inside seals, and they are easier to access for adjustment and

trouble-shooting.
