8. PORTS AND CONNECTIONS
VK Series pumps are equipped with (see fig. 4):
1. 2 inlet ports “IN”, 3/4” 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 1/2” BSP-Flange.
3. 2 service ports, 1/2”. These can be used for the pressure gauge and the safety valve.
4. 1 drain port “DRAIN” supplied with a 90o adjustable quick coupling for polyamide hoses with Ø of 10 mm. These
serve to recover drainage of the seal pack cooling circuit and must be connected to the discharge making sure
there is no back pressure.
8.1 Linings/Nose Cones
VK 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 hole the tapered lining, whenever outlet fitting or closing plug attachment is necessary, these will have to be
processed as indicated in fig. 5a.
At every disassembly, the tapered linings must be replaced.
