Germany ACTREG seals ACTREG model ACTREG price

ACTREG seals are sealing devices installed to prevent leakage between the pump shaft and the housing. Common shaft seal types include packing seals, mechanical seals, and power seals. The shaft seal of a reciprocating pump is usually a packing seal. When transporting media where leakage is not permitted, a diaphragm reciprocating pump can be used. The shaft seals of rotary pumps (including vane pumps, rotor pumps, etc.) mainly include packing seals, mechanical seals, and power seals.

ACTREG seal construction

The skeleton oil seal structure consists of three parts: the seal body, the reinforcing skeleton, and the self-tightening helical spring. The seal body is divided into the bottom, waist, cutting edge, and sealing lip according to different parts. Typically, in its free state, the inner diameter of the skeleton oil seal is smaller than the shaft diameter, meaning it has a certain "interference fit." Therefore, after the oil seal is installed in the seal housing and on the shaft, the pressure from the oil seal cutting edge and the contraction force of the self-tightening helical spring generate a certain radial clamping force on the shaft. After a period of operation, this pressure will rapidly decrease or even disappear; thus, the spring can continuously compensate for the oil seal's self-tightening force.

ACTREG seal usage guide

1) When the gearbox lubricating oil volume is ≤7 liters, the additive amount per liter of lubricating oil is 20‐30ml; 2) 7‐15 liters, the additive amount is 15‐20ml per liter of lubricating oil; 3) >15 liters, the additive amount is 10ml per liter of lubricating oil; 4) Oil seals not in temporary use should be stored properly to prevent contamination with oil, dust, or exposure to sunlight. 5) When the shaft diameter wears into a "V" shaped groove, causing the contact pressure between the new oil seal lip and the shaft to drop so that it cannot seal oil, a displacement method can be used to compensate.

ACTREG seal installation and shutdown

1) Before starting, keep the seal chamber filled with liquid. When transporting solidified media, use steam to heat the seal chamber to melt the media. Manual turning must be performed before starting to prevent sudden startup from causing the soft ring to shatter. 2) For mechanical seals using an external seal oil system, start the seal oil system first. Stop the seal oil system last after shutdown. 3) After stopping a hot oil pump, do not immediately stop the cooling water for the seal oil chamber and face seal. Wait until the oil temperature at the face seal drops below 80 degrees before stopping the cooling water to avoid damaging the seal components.
