MP Technical Data
|
|
The
UTEX MP is a straight-line, pressure-balanced seal for handling anything
from clean water to crude oil. The design features springs that are
isolated from the product to prevent clogging and fatigue. No sliding
elastomers are used that could create shaft or sleeve fretting. Solid
carbon faces are used, eliminating the need for shrink fits and allowing
easy in-plant repairs.
The seal has a slim
line design that fits AVS and ANSI pumps. The seal's integral balance
does not require stepped shafts or sleeves and can be used at operating
pressures of 0 to 450 psi. UTEX MP seals are available through 6"
sizes. Consult UTEX for specific design application information.
