Features, Advantage and BenefitsEnergy consumption, in most cases, is less than that of conventional pumping units. Nitrogen supplies approximately two-thirds of the lifting power, decreasing the horsepower requirement. • With only three moving parts (excludingthe prime mover), the VSH2 unit offers low maintenance and high reliability. Maintenance consists of just one filter per year and the normal visual inspections required of any piece of equipment.• The lightweight, compact, and uncomplicated design of the VSH2 unit minimizes site preparation, transportation, and setup costs.• Easy, variable speed control provides greater flexibility in operating the equipment and adjusting to well conditions.• Design provides versatility for pumping a wide range of wells. What is the VSH2 ? Reciprocating rod pumping unit, Operates with conventional sucker rod system, Uses nitrogen-over-hydraulic technology•Direct drive pump•Variable SPM in seconds•Greater well flexibility•Gas operatedTwo-stage cylinderNitrogen over Hydraulic AccumulatorNitrogen pressure pushes the accumulator piston down forcing the hydraulic oil from the accumulator into the upper stage of the cylinder lifting 2/3 of the rod and fluid weight.Polish rod direction is reversed via proximity switches sending a signal to the Electric Displacement Valve that changes the chamber in the lower stage to which the hydraulic oil flows. VSH2 Pumping Unit Operating Principle •Nitrogen pushes down on the accumulator piston. Hydraulic fluid under piston is forced into upper chamber thus pushing the cylinder piston up.•Servo Valve routes pressurized fluid to lower stages to cycle the cylinder up or down.•Proximity switches activate the EDC valve•Change SPM by turning switches VSH2 Benefits ✓Specifically developed for the fields with heavy crude oil, wells with rod fall problems and better well control.✓Lifts greater loads using less energy✓Handles PPRL’s up to 40,000 lbs.✓Pumps depths to 10,000 ft.✓Changes strokes per minute with a turn of the switch in either directionSrokes per Minute can be as slow as 0 and as fast as 9 (depending on model) Three moving parts •Cylinder, accumulator and direct drive pump (excluding prime mover)•Safety shutdowns •Rod separation, high pressure, low fluid level, high oil temp•SPM changes with the turn of a switch•Adjustable stroke lengths•Skid size - 5ft x 8ft x 74” VSH2 Why is this System Different ? •Nitrogen-over-Hydraulic technology•Three moving parts•Greater rod loads than conventional units•Change SPM quicker•Wider range of applications•Lower maintenance•Can reduce energy consumption•VSH2 Three Moving Parts Accumulator nitrogen / hydraulic•Cylinder two stage double acting•Pump direct drive variable speeds up & down VSH2 Control Box Panel •Off/on •Control Manual/Auto•Rod Separation•Jog up/jog down•Re-set button•Manual / auto•Power On light•Presco Press Trip•Down stroke speed control•Up stroke speed control•Auto start button VSH2 Maintenance One filter after the first 30 days and then every 5 months thereafter.Normal equipment visual inspections. VSH2 Safety Controls Low hydraulic oil level High oil temperature•Manual thermometer•Rod separation•Over torque relief valve•High pressure alarm light VSH2 Overview When to use - temporary or permanent•Well evaluating and testing•During downtime for repairs of conventional•Lengthily delivery times•Production decline to reduce energy consumption•Looking for a unit that can reduce freight,setup charges,site preparation, maintenance and energy consumption•Greater well control•Greater well flexibility Applications•Lifting of heavy crude oil in pump-to-surface applications•Correction of rod fall problems•Testing of new and re-entry wells•Short-term repairs•Wells requiring large-bore pumps NOTE: BEFORE YOU BID OR BUY. We've been under siege by buyers who purchase items and then ask to cancel sometimes after several days or even a week of nonpayment. They make claims such as "not getting financing", "being distracted then purchasing", and "not understanding that foreign purchased items require customs clearing". So lets be clear. All our items are located in a remote town in Canada, we immediately incur costs to dispatch them to the city so we can ship them timely. Large items are generally local pickup unless you can afford to wait 2-3 weeks for us to be able to ship. We are asking you not to buy any of our items if you're not committed to completing your part of the transaction; payment. We list our items with the understand of ebay policy that says "Buying an item or bidding on an auction on eBay is a commitment to complete your purchase. Even if you've changed your mind or want to cancel your order, you need to pay for your item. If you don't pay for your item the seller may open an unpaid item case against you." The reason we open an unpaid case item is to get our fees back. Keep in mind that cancelations also take a lot of our time and affects our stores standing. Our utmost appeal, again, is that you do NOT bid or buy anything from us without being sure that you're going to complete the transaction. Our team is available to answer any questions you may have before purchase. If you go a head and request a cancellation after purchase, we will report a non-payment case against you. Thanks for your understanding. Shipping: This is a large item therefore will need to be shipped by freight. All our equipment is sold as local pickups however, if you provide us ample time, (2-3 weeks) we can help with shipping. US buyers will need a customs broker (we can recommend one) and might be subject to paying an import tax. Please provide us with your address and we can work out a shipping quote from our freight service providers. Remember to research the item you buy as we offer no support or return for large equipment. You’re welcome to come see the item should you wish. Thanks
