Sucker Rod Pump Plungers

Harbison-Fischer Sucker Rod Pump Plungers are made from medium carbon, high strength steel and are spray metal coated with a nickel base coating to provide a hard, long wearing, corrosion resistant surface. The coating is metallurgically bonded to the base material with Harbison-Fischer's state-of-the-art, proprietary machines that ensure a consistent thickness and hardness for the coating. Chrome plated plungers are also available with a chrome hardness of HRC 65 minimum.

All API dimensions are adhered to and API quality standards are exceeded. All H-F plungers can be specified in .001" size increments below base size. They are available in several lengths, diameter sizes from 1-1/16" through 7-3/4" and configurations for corrosive and/or abrasive conditions.

H-F Spray Metal Plunger

This popular plunger has a hard HRC 48-52 coating and is intended for general production conditions with up to moderate corrosion and moderate abrasion.

H-F Tuffr® Plunger

The hardness of the Tuffr® plunger is HRC 58-62 and is for use in downhole conditions up to moderate corrosion and severe abrasion.

H-F Monel Pin Plunger

Severe corrosive conditions can reduce the wall thickness of regular plunger pins to where they break or develop holes. The H-F Monel Pin Plunger avoids this problem in severe corrosion by replacing the threaded ends of the plunger with corrosion resistant monel material. The sprayed metal coating is HRC 58-62 and extends to the monel pin on both ends to completely cover the plunger and protect it from corrosion. It is recommended for severe corrosion and abrasion.

H-F Grooved Plunger

Any of the above plungers can be ordered with shallow grooves spaced about one foot apart along the outside length of the plunger. The groove is cut into the plunger before coating it with the sprayed metal coating so that corrosion resistance is maintained in the grooves. Users have reported longer plunger runs with grooved plungers in abrasive conditions, especially when large abrasive particles are being produced with the production fluid.

H-F Box End Plunger

The H-F Box End Plunger is suggested for use when an end user wishes to reduce fluid friction through the plunger. The inside diameter of the H-F Box End Plunger is larger than for pin end plungers. The sprayed metal coating hardness is HRC 58-62.

H-F Pressure Actuated Plunger

The H-F Pressure Actuated Plunger is a sprayed metal plunger with either 20, 40 or 60 grooves cut into the exterior of the plunger for special split rings. It is designed for abrasive conditions that cause closely fit standard plungers to stick in the barrel during pumping. The body of the plunger is -.005" which aids in allowing particulates to pass between the plunger and barrel. The rings help lift the fluid and allow particulates to pass through the ring end gap. A variety of ring materials is available for corrosive, abrasive and/or high temperature conditions.

H-F Flexite® Ring Plunger

This plunger is designed for high water cut wells that lack enough lubrication to prevent sticking or galling of a metal plunger in the barrel. Flexite® rings are manufactured from a special hard, plastic composition material that is self-lubricating. The material is tough and wear resistant, and will not corrode, swell or disintegrate. The rings are precision ground for an exact fit in the barrel. The free moving action of the rings allows them to expand to a positive seal on the upstroke and release gradually on the downstroke. Flexite® rings are manufactured in two styles; Regular Width rings are for pumping conditions to depths of about 5,000 feet, and Wide Design (three times more sealing surface) are for deep wells and heavy loads. They are available in a wide range of sizes.

HF Composition Ring Plunger

The HF Composition Ring Plunger is a soft-packed plunger with rings that swell in downhole fluids to the appropriate tightness in the barrel. These rings are selected for use based on the gravity of the crude oil being produced and bottom hole temperature. They are intended for use when metal plungers are unable to produce the well due to sticking or galling when aggressive sands or large percentages of particulates are being pumped.

H-F Valve Cup Plunger

The H-F Valve Cup Plunger is one of the original plungers used in the first oil wells. Its use today is generally as a wiper cup plunger extension for sprayed metal plungers to help keep sand away from the wearing surface and extend the plunger's life. The cups are available in a wide variety of materials for various pumping conditions.
