Introducción

This guide will show you how to pull the riser main from the well using three lifting spanners.

This procedure requires four people: one on each of the lifting arms, and one to control the pipe vise. Communication is very important throughout this procedure. If the person handling the pipe vise opens it before everyone is ready, the riser main could drop through the vise and be lost down the well.

    • Before performing any repairs, perform a water test on the pump by raising and lowering the handle a full 40 strokes. A properly performing pump will yield greater than 10 liters.

    • Remove the hex head bolt from the top of the access door on the pump head.

    • On reassembly, this bolt should be hand-tight.
