VAC-4001/M-R 
 
M  :  The material combination of the pump. 
R  :  The assembly combination of the pump. 
 
M may be the following: 
 
A   :  Standard. Casing: GG20. Impeller: Bronze. Rotor: Stainless steel 
D  :  Casing: Rg5, Impeller: Bronze. Rotor: Stainless steel 
E  :  Special alloy. 
 
The pumps can be delivered in other material combinations, which are agreed with the supplier. 
 
R may be the following: 
 
01  :  With electromagnetic clutch. 
03  :  With hydraulic motor. 
04  :  V-belt pulley and disengaging clutch. 
07  :  On base plate with petrol or diesel engine, or with electric motor. 
09  :   With bare shaft end. 
10  :   Special-tailored according to task. 
 
Any use of the pump is to be evaluated on the basis of the materials used in the pump.  In case of 
doubt, contact the supplier. 
 
Pumps in material combinations A are primarily used for fresh water. 
Pumps in material combination D are primarily used for seawater.

TECHNICAL

 

DESCRIPTION 

The noise level of the pump depends on the motor type supplied, as the noise from the pump can 
be calculated as the noise level of the motor + 2dB(A).

INSTALLATION 

 
3.1

 

MOUNTING/FASTENING

    

 

The pump should be mounted and fastened on a solid base plate with a flat and horizontal surface 
to avoid distortion. The pump must be mounted in such a way that the shaft centerline is horizontal. 
 
When mounting a V-belt pulley on the pump a bore H7 is recommended. To facilitate the mounting 
the hub in the V-belt pulley may be heated to about 100ºC after which the V-belt pulley is easily 
lead over the shaft towards the shoulder. Alternatively, the V-belt pulley may be mounted with a 
TAPER LOCK bush.
