8. PORTS AND CONNECTIONS
SK Series pumps are equipped with (see fig. 4):
1. 2 inlet ports “IN”, 1-1/2” BSP-F.
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 3/4” HP Special.
3. 2 service ports, 1/2”. These can be used for the pressure gauge
3. 1 drain port “DRAIN” with G1/2” hole in the lower cover to moniter any water leakage due to wear of the pressure
packings. In case of leaks, please consult the repair manual.
This hole must always be kept open.
8.1 Conical seal pads/ferrules
SK pumps are provided with 4 steel conical pads, 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 conical pad, 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 conical pads must be replaced.
