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 Springs
- Pumping device independent of direction of rotation
Advantages
- Ideal seal for standardizations
- Universal applicable for packings conversions, retrofits or OEM
- No dimensional modification of the seal chamber (centrifugal pumps) 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
- Straightforward and easy installation due to pre-assembled unit
Operating range
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
