Two Stage Hollow Valve Rod Pump

Two-Stage Hollow-Valve Rod Pump V e R s A T I L e



Two-Stage Hollow-Valve Rod PumpOur mot popular pump dein

Ruggedness and versatility combine to provide the

optimal choice or most pumping conditions.

– Moves light to moderate sand without stickingwhile handling up to moderate gas-locking

conditions

– Large pull tube resists valve-rod buckling

– Shallow to deep well applications

– Insert and tubing pump congurations inmost sizes

– Uses mostly stock parts

– Available in materials and surace treatments or

corrosive or abrasive conditions

The Two Stage Hollow-Valve Rod Pump uses two-

stage compression technology to avoid gas locking.

Here’s how: On the downstroke, the upper traveling

valve holds back the hydrostatic head and allows

the lower traveling valve to open without the need to

compress the fuid/gas mixture to a high pressure.As the downstroke continues, the fuid/gas mixture

rom the lower compression chamber moves through

the plunger to the upper compression chamber. At

the start o the upstroke, the lower traveling valve

closes and the standing valve opens to admit newfuid to the lower compression chamber. During the

upstroke, the fuid/gas mixture in the upper compres-

sion chamber is compressed to a higher pressure

until the top traveling valve opens and allows the

fuid to be discharged into the tubing above the

pump completing the pumping cycle.

The pull-tube guide has a generous clearance to

allow sand and other particulates to be fushed rom

the upper compression chamber during the upstroke.

This characteristic gives the Two-Stage Hollow-Valve

Rod Pump its versatility in gas-locking applications,

which also produce sand or other particulates.

Variable Slippage Pump® (VSP)



Variable Slippage Pump®

(VSP)(Patent Number 6,273,690)

Fine-tune your VsP® to uit your well

– Eliminates gas locking, fuid pound and

gas pound

– Adjustable slippage to match needed

gas handling

– Easy to adjust by raising or loweringpolished-rod clamp

– ed minimum polished-rod load or greater

sucker-rod lie

– Corrosion- and abrasion-resistant materials

available

The patented Variable Slippage Pump® is a sucker-

rod-drawn, positive-displacement pump which oper-

ates on the principle o pressure equalization just

beore the plunger reaches the top o the upstroke.

Existing pump designs rely on the ability o the

pump to produce high pressure in the compression

chamber during the downstroke. This high pressure

is needed to open the traveling valve and allow fuid

and gas to fow through the plunger or liting to thesurace on the upstroke. Failure o the traveling valve

to open on the downstroke in gassy wells causes a

gas-locked condition and no production.

The VSP® has a gradual taper in the upper barrel.

As the plunger enters this taper near the top o theupstroke, slippage increases past the plunger, and

pressure is equalized above and below the plunger

and traveling valve. Thereore, when the plunger

starts downward, the traveling valve opens easily

since high pressure in the compression chamber has

already been achieved.

Pampa Gas Pump®

The bet o both world –

a and and handlinin the ame pump

– Reduces sticking rom sand or other particulateswhile increasing the compression ratio or ewer

gas problems

– Increases run time because o large plunger and

barrel wear areas

– Materials or abrasion and corrosion available

For many years, the traditional Harbison-Fischer

Pampa Pump with its long plunger and short

barrel has been a resounding success in solving

particulate-production problems. The Pampa Gas

Pump® is a modied Pampa Pump characterized bya long barrel and long plunger but without a lower

extension. The absence o a lower extension and

the addition o compression-chamber-enhancing

eatures signicantly improve the compression ratio.

This creates a pump that is designed or pumpingproblems up to and including severe particulates

and moderate gas locking. The Pampa Gas Pump®

will load the pumping unit and produce fuid in the

same manner as any API pump.

Gas Vent ™ Pump e F F I c I e n T



Gas Vent ™

Pump

Pumps your well downfurther and separates the gas

– Avoids gas locking and gas intererence byventing gas rom the fuid beore it is pumped up

the tubing

– Maximizes production with the lowest drawdown

o casing fuid level o any pump. Produces fuid

at zero-intake pressure– Slow pumping speeds not a problem

– Choice o insert- or tubing-style pump

– Materials for corrosive and abrasive environments

available

The patented Gas Vent™ Pump is a new concept

in sucker-rod pumping. It separates gas from fluid,

producing gas up the casing/tubing annulus and

almost gas-free fluid up the tubing. The unique

gas-separating aspect of this pump is that the lower

plunger passes above the vent ports on the upstroke.

This allows gas to escape from the compression

chamber to the casing. The traveling valves open

on the downstroke when the lower traveling valve

contacts the fluid and the fluid forms a fluid seal

between the lower plunger and lower barrel.

Note that the upper, soft-packed plunger always

strokes above the vent ports and holds back the

hydrostatic pressure above the pump.

– Reduces gas locking due to a compound

compression ratio that can produce almostpure gas

– Versatile applications or deep or shallow wells

– Available in materials and surace treatments or

abrasive and corrosive conditions

The Harbison-Fischer Gas Chaser Pump is designed

or the very worst gas-locking problems that are

encountered in rod-pumped wells. It is similar in

design and theory o operation to the Two-Stage

Hollow-Valve Rod Pump and achieves a higher

compression ratio by using an absolute seal at thetop o the upper compression chamber. The Gas

Chaser Pump transers the fuid/gas mixture to the

upper compression chamber on the downstroke and

produces this fuid through the hollow upper plunger

on the upstroke. The highest compression ratio isachieved by spacing the pump rom the top.

Loc-No® Plunger Travel No-Loc Valve



Loc-No®

PlungerThe etablihed olution

to a lockin

This simple plunger assembly solves the complex

problem o gas locking.– Diminishes gas locking with a mechanically-

opening traveling valve

– Long-wearing, hard inlay on sealing suraces

– Complete plunger assembly simplies installation

The Loc-No® Plunger is assembled with a hollow-

plunger sleeve, a center connecting rod, an upper

connector and a lower drop to seal against the

bottom o the sleeve on each upstroke o the

pump. It has two characteristics that enable it to

open on the downstroke without relying on pump

compression. The movement o the plunger rod

pushes the drop away rom the plunger sleeve,

and the riction between the plunger sleeve and the

inside o the barrel tube causes the plunger sleeve toresist downward movement.

Travel No-Loc Valve

Freedom rom a lockin orthe travelin-barrel pump

– Reduces gas locking with a mechanically-opening

traveling valve

– Long-wearing, hard inlay on sealing suraces or

long run times

The Travel No-Loc Valve is an adaptation o the

Harbison-Fischer Loc-No® Plunger concept or a

traveling-barrel-pump design. This device gives the

traveling-barrel pump an opportunity to work withoutgas locking while retaining all o the advantages o

a common traveling-barrel pump. Easily adapts to

the top o all traveling-barrel pumps.

Sliding Top Valve



Sliding Top Valve A imple and ecient olution

or a lockin andfuid-pound condition

A avorite accessory that helps your pump workmore smoothly and produce more fuid in gas lock-

ing and fuid-pound problem wells.

– Isolates hydrostatic pressure rom your

traveling valve to enable its opening in

gas-locking conditions

– Cushions fuid pound to avoid damage

to your pump

– Long-wearing, hard-bronze sliding sleeve

can be abrasion-resistant coated or tough

sand production– Easy pump conversion

– For insert and tubing pumps in all sizes

– Corrosion-resistant materials available

The Sliding Top Valve has a ree-foating, hard-bronze sleeve that rides up and down on the valve

rod in a steel housing. On the pumping downstroke,

the sleeve ollows the valve rod down and seals o

the hydrostatic pressure rom above by shutting o

the fuid-fow passages through the housing. This

simple action removes the hydrostatic pressure load

rom the traveling valve and allows it to open at

the beginning o the downstroke without the need

to build up a high pressure in the compression

chamber.

The Sliding Top Valve is also useul to cushion fuid

pound. A part o the downward orce that causes

the destruction associated with fuid pound is the

hydrostatic pressure above the plunger acting on

part o the plunger area. The Sliding Top Valve holds

back this hydrostatic head and thus reduces the loadon the plunger when it contacts the fuid.

– Dumps sand rom your mud anchor

– Simple, dependable design

The Tubing Purge Valve is used when fuids are

produced that contain both gas and sand. It is

installed on the bottom o the mud anchor below the

gas separator to replace the bull plug. The ball and

seat are held closed with a lightly loaded, corrosion-

resistant spring. When the high-pressure fuid surgeoccurs during the closing o the standing valve,

the Purge Valve ball pushes o its seat briefy and

“dumps” any sand or other particulates.

Bypass Seating Nipple(Patent Number 5,176,216)
