3.18.5.4 Strainer
Foreign particles can seriously damage the pump. Avoid the entry of these particles by installing a
strainer.
• Whenselectingthestrainerattentionshouldbegiventothesizeoftheopeningssothatpres-
sure losses are minimised. The cross-sectional area of the strainer must be three times that of
the suction pipe.

• Makesurethatthepressuredropinthestraineriscalculatedwiththerightviscosity.Heatthe
strainer if necessary to reduce viscosity and pressure drop.
For the maximum allowable particle size see section 3.15.
3.18.6 Secondary piping
For dimensions of connections and plugs see chapter 6.0.
3.18.6.1 Drain lines
The pump is provided with a drain plug.
3.18.6.2 Heating jackets
1. S-type jackets
The S-jackets are designed for use with saturated steam (max 10 bar, 180°C) or with non-dangerous
media. They are provided with threaded connections Bl (see chapter 6.0 for the dimensions).
The connection can be done by threaded pipes or pipe connections with sealing in the thread
(conical thread applying ISO 7/1) or sealed outside the thread by means of flat gaskets (cylindrical
thread applying ISO 228/1). Thread type see section 3.21.7.
