Seepex는 과거 trigem(3면)형태의 이송 방법을 6L(6면) 이송방법으로 발전시켜
안정된 연속성확보, 수명연장, 유량증가 등의 기술을 확보 하였습니다.
6L-geometry
As compared to the conventional geometry, the rotor of the 6L-geometry features
a larger pitch and at the same time a smaller diameter and smaller eccentric.
The resulting longer sealing line as well
as the surface velocity decreased by 20 % drastically increase the service
life as compared to the conventional geometry. Even with proceeding wear,
the conveying capacity and feed pressure are kept constant over a long
period of time.
A smaller pressure working surface results
from the geometric changes on the rotor diameter and eccentricity. This
leads to lower axial forces on the joints and the pump bearings. With
conventional geometry the axial forces are up to 50 percent higher.
The stretched geometry provides for the optimised
flow curve that has a positive effect on pulsation and vibration.
Tricam Geometry
The Tricam geometry is the conclusive further development of the 6L-geometry.
At an identical speed, the conveying capacity is increased by 50 %.
The double-helix rotor features an elliptic cross section that rotates in
a triple-helix stator featuring the same geometrical ratio. As compared
to the rotor, the number of helices of the stator is 1,5 times higher. The
helices are staggered by 120 degrees and feature 1.5 times the pitch length.
The Tricam geometry creates an additional conveying channel.
Dimensional similarity makes it possible to
convert the pump from 6L to Tricam geometry.
