It is equivalent to Burgmann H75 and used for Vortex pumps.
It repace burgmann H75 type. ingle seal,independent of direction of rotation,
conform to EN12756 (DIN24960),push ring was stuck by drive sitting to avoid
spring fall off. Make stationary ring fixed,limit spring's move to avoid carbon
ring excessively abrasion.
Same as H7N, just with multiple springs in sleeves.
H7N Machined Mechanical Seal
(Replace BURGMANN H7N)
H75 (Replace BURGMANN H75, MTU DR1-HS))
our Mechanical seal model H7N can Replace BURGMANN H7N.
our Mechanical seal model H75 can BURGMANN H75 and MTU DR1-HS
.
we also can make changes as customers'requirement or totally
design a new type of mechanical seal to meet clients'needs.

it can replace most model of single coil spring, multiple spring and wave spring
mechanical seal. Bellows is made from low-cost metal bellows mechanical seal
but high performance, robust design and reliable for general applications.
It is of non-thrust construction without slip seal ring, free of compensated loop,
avoiding friction with shaft or shaft sleeve.Having excellent matching property,
its jackscrew positioning widens its adjustment range.
The revolving design enables the bellows to perform its function of self-cleaning
which will avoid its blocking and loss of elasticity.
