Pump type

Winter weather and safe flying are not a sure combination. Ice on an aircraft’s wings or tail alters the aerodynamics and adds undesirable weight. Ice and snow falling off the plane can end up in the engines and even damage the tail. For fully loaded planes this can have severe consequences when taking off, making de-icing aircraft in winter essential. Safety first! And that means using SEEPEX pumps.

Background

Just before takeoff, jets are sprayed with a glycol-based de-icing mixture which had been pumped onto special utility vehicles. Complete reliability is required, as takeoff delays due to pump failures must be avoided in order to maintain tight flight schedules. 

Task

The key ingredient, glycol, requires extremely careful treatment. The pumps have to minimize the shearing effects on glycol in order to avoid destroying its molecular structure. 

Solution

Winter after winter, SEEPEX progressive cavity pumps from the BN range dependably pump heated de-icing fluid from tanks into de-icing vehicles.

"Quite simply, at SEEPEX we know precisely in what manner sensitive products need to be moved. This enabled us to offer the airport operators an effective solution."

Dr. Christian Hansen
Director Engineering, SEEPEX GmbH

The design of rotor and stator ensures proper handling of the glycol-containing agent, which is very gently moved through the chambers. The huge advantage is that the de-icing fluid sticks better to the aircraft body during takeoff.

Benefits

he damage-free pumping operation is what convinced the operator to use this technology, as aircraft safety is paramount.

"SEEPEX pumps are an all-around reliable and cost-effective technology for airport winter operations."
