8. PORTS AND CONNECTIONS
SM Series pumps are equipped with (see fig. 4):
1. 2 inlet ports “IN”, 1-1/2” Gas
The line can be connected to either of the two inlet ports; the ones not being used must be hermetically sealed.
2. 2 outlet ports “OUT”, Ø 13mm
3. 2 service ports, 1/2” Gas. These can be used for the pressure gauge
4. 1 drain port “DRAIN” supplied with a 90 o adjustable quick coupling for polyamide hose with Ø 12mm. These allow
drainage recovery of the seal pack cooling circuit and must be connected to the discharge, making sure that there
is no back pressure.
8.1 Linings/Nose Cones
SM pumps are provided with 4 steel tapered linings, for use in the corresponding outlet ports of the pump (see fig. 5)
or in the optional connection flanges, to ensure the connection seal. While the seat of the pump’s outlet port is already
machined to accept the tapered lining, if it is necessary to make the connection for the outlet connection or the closing
plug, these must be specifically machined as shown in fig. 5a.
At every disassembly, the tapered linings must be replaced.
