Mechanical Seals from Burgmann

Valley Equipment is proud to offer EagleBurgmann Mechanical Seals and Products.
As a first class seal and support system manufacturer, EagleBurgmann will have a solution to any of your sealing needs on pumps, mixers, agitators, compressors and much more.

Cartex Seals For Centrifugal Pumps

Cartex® mechanical seals are fully preasembled. They are balanced, can be used in either direction of rotation and come with all the connections you need for the most common modes of operation.

Operating Limits

d1 = 25 ... 100 mm (1" ... 4")
Larger diameters on request

t = - 40 ... 220°C
(check O-ring temperature resistance)

Gas Lubricated

■ ASGSD
■ ABGSD Double Gas Seals

A design combination of stationary springs and seal faces pressurized from the inside, this seal can handles solids up to 3% in confined seal chambers. Standard bi-directional grooves forgive incorrect electrical motor installation and backflow of product. this seal fits most ANSI seal chambers (standard and enlarged) without modifications or replacement.

Liquid Lubricated - Single Seal

■ ASPN (Standard Bore)
■ ABPN (Big Bore)

Balanced, bi-directional seals with a flush connection in the flange. Available in small bore (ASPN) and big bore (ABPN) configurations.

Liquid Lubricated - Quench Seal

■ ASQN (Standard Bore)
■ ABQN (Big Bore)

ASTN & ABTN are designed for operating with an internal steam quench. Flange includes a fixed carbon throttle bushing which also acts as a "disaster bushing". In the event of primary seal failure, the bushing holds pressure and the drain port directs leakage to a defined location to provide an additional safety option. Available in small bore (ASTN & ASQN) and big bore (ABTN & ABQN) configurations.

ASQN & ABQN has lip seal in place of throttle bush & allows for using a pressureless liquid internal quench.

Liquid Lubricated - Double Seal

■ ASDN (Standard Bore)
■ ABDN (Big Bore)

Available in small bore (ASDN) and big bored (ABDN) configurations. Patented integrated circulating device for effective cooling. Can be used as double or tandem seal. The double balanced inboard face design ensures that the seal faces remain closed even in the event of buffer pressure failure or pressure reversal.

Splitex ®

Fully split cartridge seal for pumps

Splitex®, a fully split mechanical seal, is suitable for pump applications in many sectors of industry such as water and waste water treatment, pulp and paper, power generation, mining, shipbuilding, textiles and process engineering.

Under certain circumstances, repairing a pump can give rise to costly and extensive downtime and assembly time, for instance when there is too little space for installing or changing a seal, or if there is no quick-change facility, or if a pump is operated without
stand-by. The fully split, pre-assembled Splitex® only has the dimensions of a flange and is ideal in such cases. All it takes is to lay the half-shells around the shaft and bolt them together. Any packing rings can remain in the stuffing box compartment.

		Single seal, fully split into 2 x 2 segments, pre-assembled
		Balanced
		External pressurization
		Springbacking stationary, protected from the product
		Rotating seat (torque transmission to shaft with clamping ring, mechanically decoupled)
		Easily removable assembly clips enable self-centering when being installed
		None of the joints require secondary seals
		Housing and mounting parts sealed metallically by way of lapped surfaces
		Seal faces by way of the natural internal structure
		O-ring by way of precisely defined pressing action (no adhesion, no special mating)

Operating Limits

d1 = 50 -150 mm (2" - 6")

p1 = 6 -10 bar

t1 = ... 150 °C

vg = 10 m/s

Mtex ®

Metal bellows cartridge seal

Metal Bellows technology tried-and-tested in service with a wide range of operating temperatures. State-of-the-art sealing technology, also availble in a gas lubricated version.

Large temperature operating range (-40 ... +280°C). Simple and rugged design, extremely easy to install. Equally ideal for retrofits and original equipment.

		Single seal with throttle bushing for gas and steam quench (Mtex-TN)
		Same design as Mtex-TN -additionally with multipoint injection for equal distribution of flush liquid acc. to API regulations (Mtex-TNM)
		Single seal with lip seal for liquid quench (Mtex-QN)
		Same design as Mtex-QN- additionally with multipoint injection for equal distribution of flush liquid acc. to API regulations (Mtex-QNM)
		Double seal with metal bellows seal on the product side and stationary O-ring seal on the atmospheric side (Mtex-DN), pumping device independent of direction of rotation for barrier/buffer fluid

Operating Limits

d1 = 25 - 80 mm (0.9" - 3.15")

p1 = 25 bar (360 PSI)

t = -40°C - +280°C (-40°F - +536°F)

vg = 15 m/s (15 ft/s)

Max. axial movement: ± 0.5 mm

HS-D

Mechanical seal for top entry drives

Vessels seals of the HS-D range are designed for medium-to-high pressure applications. HS(L)-D, unbalanced, for up to PN 25. Operation only with pressurized buffer fluid. Additional options and several torque transmissions are available.
		Double seal
		Cartridge unit
		Independent of direction of rotation

Supply Systems
EagleBurgmann also manufactures supply systems and the supporting hardware for liquid-lubricated mechanical seals. Seal pots, barrier fluid booster pumps and hydrocycle seperators are just a small example of the full line of accessories for mechanical seals.
