As a patent product of our company, VertiLift long stroke pumping unit have been applied in oilfield since 1984, and more than 3,000 sets of VertiLift pumping units have been installed in the oilfields of Sinopec, CNPC in China, as well as in Uzbekistan, Canada and Mexico.

                                                    VertiLift Pumping Units in 1980s                                                                                 Present Unit

According to the differences of peak polish rod loads (PPRL) and gearbox rated torques and strokes, the VertiLift pumping units can be divided into 8 kinds of models.

Gear Reducers

VertiLift Gear Reducer Advantages

1. The double circular arc gear reducer, smooth transmission, low noise and vibration, whose bearing capacity, wear resistance, contact fatigue life and temperature rising are better than that of the common involute gear, is more suitable for pumping unit with low-speed, overloading and continuous working condition. 

2. The gear reducer housing is made of high quality steel plate welding and leakage test will be carried; compared with the casting housing, the bearing capacity is larger and strength is higher. 

3. The gear reducer output shaft is made of alloy steel and nondestructive detection will be conducted, meanwhile, the distance of two supporting points distance widened to better adapt to the reducer cantilever stress structure and improve the strength & bending capacity.

4. The gear reducer adopts external-contacting braking, convenient adjustment and has reliable braking effect. In addition, we can also provide a set of automatic braking system according to user requirements.

Main Advantages of VertiLift Pumping Unit

1. Long, Slow Strokes: Long strokes lead to high pump fill and less fluid impact; Slow SPM means less wear on down-hole equipment and less operational cost.

2. Belt Transmission: Power is transmitted by a long life heavy-duty belt, whose elastic cushion effectively absorbs impact in reverse action and results in a uniform reciprocal movement of the rod string.

3. Low Torque Demand: The torque demand is greatly reduced. Therefore, smaller prime mover and gear box is possible, which can cut down energy costs by 10% to 30% compared to other manual lift systems.

4. Adopt Symmetrical Balance, Mechanical Balance. The counterweight can be adjusted simply and conveniently.

5. Safe and Easy Operation due to Optimum Structure Design: Two sets of brake systems with the automatic braking device ensure the units absolute safety; enclosed unit design allows the unit to be folded up for convenience during shipping and allows it to be moved safely.

6. High Reliability and Minimum Maintenance: The antifriction bearings, a long life belt and heavy load roller chains are adopted to ensure unit reliability. The optimized lubrication system and automatic protective device as well as the enclosed unit can reduce the frequency of repairs and maintenance.

7. Fairly Complete Production Supporting System. The system ensures the unit can be used with big pumps for more fluid lift and small pumps in deep well applications.

Applications of VertiLift Pumping Unit

As a patent products, VertiLift is a 100% mechanical driven pumping unit. It is especially suitable for using with big pumps for more fluid lift, small pumps in deep wells and also heavy oil recovery applications. Now VertiLift pumping units have been expanded to 8 models, and the maximum peak polish rod loads range from 22,046 lbs to 57,320 lbs and strokes from 197 inch to 354 inch. Equipped with advanced technology, the pumping unit always brings good economic benefits to clients by offering highly efficient, reliable, safe performance both at home and abroad.

1. Substituting Electric Submersible Pumps. Matching φ70～φ120 large pump, the pump depth of the pumping unit can achieve 1500~2700m, the theoretical liquid producing capacity is 550 cubic meters per day.

2. Using Small Pumps to Pump Deeply. Mating φ32～φ44mm small pumps, the pump depth of the pumping unit can achieve 4000m.

3. The Exploitation of Heavy Oil Wells. According to the user’s program of special oil wells, the units can configure the automatic control system based on oil well loading changes to adjust the real-time speed and the real-time stroke. Mating the oil recovery processes like hollow rod electric heating, mixing light oil, water, SAGD and so on.

4. Application of Cluster Wells. These wells give full play to the advantages of the compact structure and the small areas of the pumping units. They are widely used in artificial islands, residential areas, cluster well sites and other restricted areas.
