Product Description

Product Description

(1) Features
•Double seal
•Mtex-DN: API Plan 52 (53/54)
•Mtex9-DN: API Plan 53/54
•Cartridge
•Balanced
•Independent of direction of rotation
•Metal bellows
•Stationary O-Ring
•Pumping device independent of direction of rotation


(2) Advantages
•Ideal seal for standardizations
•Universal applicable for packings conversions, retrofits or OEM
•Suitable for high temperature
•No dimensional modification of the seal chamber necessary, small radial installation height
•Trouble-free running due to bellows unit with vibration dampers (essential in case of dry-running)
•No damage of the shaft by dynamically loaded O-Ring
•Self cleaning effect of the bellows
•Installation faults are avoided, cost-effective
•No damage caused by dirt entered during assembly
•Straightforward and easy installation due to preassembled unit (reduced down-times)
•Individual adaptation to pump design possible


(3) Operating range (see note on page 1)
Shaft diameter: d1 = 25 ... 80 mm (1"...3.15")
Temperature: t* = -40 °C ... +220 °C (-40 °F...+428 °F)
Pressure: p1 = 25 bar (232 PSI)
Sliding velocity: vg = 20 m/s (66 ft/s)

Barrier fluid circulation system:
p3max = 16 bar (232 PSI)
Δp (p3 - p1) ideal = 2 ... 3 bar (29...44 PSI)
Δp (p3 - p1) max. = 10 bar (145 PSI) at < 120 °C
(< 248 °F), = 5 bar (73 PSI) at ≤ 220 °C (≤ 232 °F)

API Plan 52 (53/54)

Pump startup:
Δp (p3 - p1) max = 16 bar (232 PSI) allowed
* Operating limits of O-Rings to be observed

Secondary seals: FPM (V), EPDM (E), FFKM (K)
Bellows: Inconel 718 (Mfb)
Springs: Hastelloy C-4 (M)
Metal parts: CrNiMo steel (G), Duplex (G1)


(8)Product variant
Mtex9-DN
Dimensions, items and descriptions as for Mtex-DN,
but with optimized seal face geometry for pressurized
operation according to API Plan 53/54. A barrier fluid
system (e. g. EagleBurgman TS2000) is necessary.

Pressure: p1 = 10 bar (145 PSI)
Sliding velocity: vg = 20 m/s (66 ft/s)

Barrier fluid circulation system:
p3max = 1fb bar (232 PSI)
Δp (p3 - p1) ideal = 2 ... 3 bar (29 ... 44 PSI)
Δp (p3 - p1) max = 16 bar (232 PSI)

API Plan 53/54

Pump startup:
Δp (p3 - p1) max = 16 bar (232 PSI) allowed
