5.2.5 CONNECTIONS
- Discharge flange axis is vertical and flange face is horizontal.
Other variants are available upon request. Pump complete
description is given in pump technical datasheet or in the
aknowledgement of order.
5.2.6 PERMISSIBLE FORCES AND MOMENTS
No other stress than the one due to fastening of pipe and pump
flanges together should apply. No stress must be applied to pump casing
by the pipe work. A pre-stress may exceptionally be applied to flanges to
compensate a pipe expansion. But in any case the resulting forces should
not exceed values given hereafter.

SUCTION:
No load is allowed on the suction port. It should be used only to connect
strainer or extension pipe.
5.2.7 SCOPE OF DELIVERY
Pump can be delivered as a complete pump set including electrical
motor, flexible coupling, coupling guard and baseplate. It can be also
delivered without one of those parts. A CE integration certificate is then
supplied.
This instructions and operating manual is part of the pump supply and
should be delivered attached to the pump. If not, ask WILO Customer
department to get it.
ATEX pumps may be delivered with specific instrumentation. Refer
to pump technical datasheet or to acknowledgment of order to know
exhaustive scope of supply.
6 DESCRIPTION AND WORKING PRINCIPLE
6.1 PRODUCT INFORMATION
Norma V pumps are pit pumps with dry motor. The centrifuge hydraulic
has vertical inlet and radial outlet. A discharge pipe is integrated to allow
hydraulic connection above mating plate.
Integrated support clamp can be used for direct installation (assembly
type CS). Pumps can be fitted with a rectangular mating plate fully
adaptable to customer needs (ISO or ANSI, special shape, …)
Shaft bearings can be lubricated by the pumped fluid or another fluid
available on site.
Different assembly variants exist for drives. Motors frames are V1 or V18
according to IEC standard.
6.1.1 MOTOR ASSEMBLY TYPES :
6.1.1.1 MOTOR ASSEMBLY TYPE CS :
A clamp is fastened on pump column and allows easy adjustment of
pump length under mating plate. The drive is directly fastened on upper
column flange. Maximum installed power is 9KW for this design. A rigid
coupling keyed onto pump and motor shafts is used for power
transmission. Size “O” smaller than 1300mm.
