In the UP-Do Pump Series, the motor power is transmitted without slip directly to the pump impeller with a rigid shaft (no magnetic coupling). A double mechanical seal (back to back) prevents the leakage of the media to be pumped and ensures the leak proof sealing of the centrifugal pump. All parts that are in contact with the medium are made solid of stainless steel (1.4581). The cooling and lubrication of the mechanical seals is carried out through a separate seal water circle.

Advantages of the UP-DO Pump Series:

- with a connected seal water circle, the pump cannot be damaged, neither through   operator error or malfunctions in the plant (dry run safe under certain conditions). - applicable for media without lubricating properties (e.g. varnishes and paints) - also applicable for higher viscosities or metallic particles in the medium - the highest chemical resistance also at high temperatures up to +150° C - robust, thick-walled design, solid stainless steel fine cast (no thin-walled extruded   sheet metal) - low-maintenance through an optimal adaptation to the medium to be pumped - long-lasting and wear resistant, various types of designs for almost all operating   conditions - open impeller (i.e. solids up to 3 mm grain size and 10 Vol. % possible) - easy to maintain (wear parts and the mechanical seal can be changed swiftly) - universally applicable, quiet and compact - various chemical resistant materials can be supplied as stock items

This results in application possibilities, amongst others, for the following application fields:	- Circulation pump for heat exchanger - Use for very hot alkaline liquids - Laboratory applications - Environment engineering - Paper manufacturing		- Electro-plating technology - Airplane jet engine cleaning plants - Filtration - Food industry - Varnish processing operations
	- For soiled and metallically contaminated media
