How do you space out fiberglass rods?

A tested formula for pump spacing with Fiberflex® fiberglass sucker rods is as follows: (9” X Footage of Fiberglass Rods) + (2” X Seating Nipple Depth) 1000 1000 When spacing a pump, it is important to stack-out the rod string to ensure the pump is properly seated.

How long are fiberglass rods?

In specific applications, fiberglass sucker rods are an optimal choice because they lighten the load in the rod string and stand up to corrosive wellbore fluids. At 37-1/2 ft (11.4 m) long, our fiberglass sucker rods have fewer connections, which significantly shortens pull times.
