General description
ViscoTwin
Screw pumps are rotating displacement pumps for delivering low to highly viscose media.
Pumps for use in the foodstuffs and beverage industry are designed and built to the
recommendations of DIN EN 1672-2 ‘Food processing machinery - Basic concepts’. This does not
include pipe connections, which require special cleaning procedures. These must be cleaned
manually by the operator. The cleaning cycle is dependent on the food and the relevant hazard from.
This is set by the operator. Correspond to the pipe connections according to DIN 11864, according
to DIN EN 1672-2 there is no health risk. The operator does not define any special cleaning
measures.
Non-corroding materials suitable for cleaning and/or disinfection are being used for the product-
contacting parts of these pumps. Elastomer materials and seals correspond to the BfR (German
Federal Institute for Risk Assessment) recommendations and the FDA guidelines respectively (US
Food and Drug Administration) and the Regulation (EC) No 1935/2004.
The pumps and pump units respectively are designed and built taking the health and safety
requirements of the EC Machinery Directive into account
w
ith all requirements met, either the EC
Declaration of Conformity (with CE mark) or in the case of partly completed machines, a Declaration
of Incorporation is issued.

is assuring the conformity of 3-A standard 02-11 for the pumps delivered to 3-A

Sound emission
Each pump is manufactured and tested acc. to the currently valid technical documentation. The
weighted continuous sound level is normally <70 dB(A) with drive and pipe lines not included in this
measurement. Cavitation-free operation and proper fastening of the pump unit on level concrete slab
or warp resistant steel structure is taken for granted.
