Our pump for your process!

The demand for melt pumps has risen dramatically in recent months. The reason for this is the corona pandemic and the increased demand for medical nonwovens produced by the melt-blown process using these pumps.

Many manufacturers were only able to offer these pumps with many weeks delivery time due to the high demand. We have used the last weeks to hold intensive discussions with existing suppliers and to engage new additional suppliers for the core components of our pumps.

From now on we have a selection of the most common sizes of the EXTRU III melt pump in standard design in stock and can deliver small batches with shortened delivery time.

Inquiries from our network of representatives will be given preferential treatment. We have already informed our customers about the shortened delivery times. The melt pumps are available on call at the WITTE site in Tornesch.

The EXTRU series has been established for years in a wide range of extrusion processes and is used in a variety of applications. For the sizes listed below, spare parts in standard design are of course also available from stock.
The following sizes are available:
