Frontline Industries, Inc. products

Frontline has the capability to design, manufacture and install mechanical seals for “hard to seal” applications. Frontline can also overhaul and test most manufacturer’s mechanical seals. During the overhaul process we will ask the customer several questions regarding the specific application so that, if required we can improve the seal characteristics accordingly.

The Single Engagement Design is comprised of two hubs – one containing pins and one containing bushings. This arrangement can only accommodate Angular and Axial Misalignment.

Our carbon fiber drive shaft can be provided with any combination of hubs with pins or bushings depending on the field conditions.

Frontline Couplings transmit torque through precision machined barrel shaped pins, which ride within self-lubricated fiber-reinforced polymer bushings. This patented “free-floating” double engagement design gives the Frontline Coupling several advantages.

Our unique patent pending mechanical seal cooler, which we manufacture in house. Is designed for boiler feed pumps and is rated for: 400°F & 500 P.S.I. We recommend a hot water flow of 2 G.P.M. at about 140°F going into the mechanical seal glands
