Notes:
1、Check carefully before install the pump body abortion in presence of rigid objects, to avoid damage to the impeller and the pump body when running。
2、Piping installation quantity are not allowed to add on the pump, lest make pump deformation, affect the normal operation。
3、Tighten the anchor bolts, in order to avoid starting when the vibration impact on pump performance。
4、On the road at the inlet and outlet pipe of pump install regulator installed near the pump outlet pressure gauge, to control the operation of the pump in rated conditions, to ensure the normal use of the pump。
5、Discharge line such as loaded check valve should be installed outside the gate。
6、Pump installed installation is divided into rigid connection and flexible connection。
