More Oil ... Less Water!
Improve Stripper Well Performance Through Micro-Pumping
 
Here's what makes MK's Rhino MiniJack different
Unique, Fully Enclosed Above-Surface Drive Motor
  • Field-serviceable top-head-drive motor is mounted just above the pumping unit and the oil being pumped, resulting in extremely dependable, efficient and easy-to-control mechanics, with simple servicing
  • State-of-the-art, programmable-logic controller tightly manages pump activity and reduces operating costs, while built-in communications port offers easy off-site computer monitoring
  • Weather-resistant actuators are built for extreme conditions
  • Unlike bulky heavy iron, the Rhino MiniJack has a remarkably low profile and small footprint
  • The Rhino MiniJack is simple to install and easily portable, weighing less than 125 pounds
  • Patent-pending stuffing box prevents surface leaking and allows fast surface change-outs
  • These positive-displacement pumps provide optimal flow rates and can pump uniformly against high head, independent of the liquid head in the well
Stainless Steel Downhole Pump Barrel
  • The Rhino MiniJack's downhole pump features a machined, rolled and welded stainless steel pump barrel with standing valve, plus a stainless steel check ball and seat to ensure no-leak performance and long life
  • Stainless steel pump barrel stands up to tough chemical, gas, grit and silt environments
  • Downhole pump barrels are in broad service, with millions of successful pumping hours
Patented Traveling Valve
  • Made of low-weight, high-strength, low-friction material or brass, depending on downwell temperature and chemistry
  • Field proven to provide extended service life
  • Low-friction material is ideal for applications requiring resistance to abrasion
  • Seals are easily replaced
  • Lightweight unitary drive rods have the strength to go deep, yet allow the pump to work more efficiently and economically, with lower horsepower
  • MK Rhino MiniJack pumps are adaptable to existing tubing and well heads
Multiple downhole pump sizes, depending upon pump volume and depth
  • Choose up to 15 bbl/day to depths of 1,500 feet using 3 hp electric motor, or up to 15 bbl/day to depths of 750 feet using 1 hp motor
  • Solar and Pneumatic Motor Option
Patented Drive Rod and Connector
  • Unitary fiberglass rod is high strength and low weight, which allow fast installation at low cost
  • Continuous drive rod up to 1,500 feet
  • Highly reliable reinforced rods run cleanly and easily, and are designed for the most demanding situations, including hot, viscous oil wells
Fully-enclosed top-head-drive motor offered in standard or explosion-proof versions
  • Explosion-proof electric motor option meets U.S. Class 2, Div. I requirements
  • All-weather actuator stands up to extreme hot and cold environments
  • Top-head-drive actuator motor is mounted on top of well head, and is fully field-serviceable
State-of-the-Art Programmable Logic Controller (PLC) Option
  • Choose easy-to-use pump time and dwell set-up with external communication port - allowing you to decide speed, time between pumps, and time of day, week or month to pump
  • Pre-program speed, hour run time, stroke count, dwell delay time for both up and down stroke, auto restart if electric service interrupted, time-of-day on/off
  • Match production with actual well inflow by changing pump cycle time in the well or through continuous altering of pump speed
  • Accurately control rod pumping system, determining when pump needs to run to reduce utility costs
  • Actuator and control work together to reduce rod load and torque, resulting in lower horsepower requirements
  • Built-in communications port allows operator to monitor, manage and optimize Rhino MiniJack pumps from a single, off-site control point
  • Pump and controls come ready to plumb and plug in
Customizable
  • Choose a standard unit or mix and match components for individual needs
