Prep prime pump
2
Q
Limiting factors in drafting
A
Water available from draft
Capability of the pump
3
Q
Water available from draft
A
Focuses on intake side of the pump
Height of lift and altitude
Diameter and length of hard suction
4
Q
Capability of the pump
A
Amount of work the pump can do
Size of the pump
RPM should never exceed 2000
Changes in PDP only alter capability of the pump
5
Q

A
PDP and quantity of flow must be known
Capability of the pump is sufficient and available water from draft is equal or greater to capability of pump
6
Q
