well as gas well dewatering. It iscapable of handling a wide range offluids from water and light crudes tohighly abrasive heavy oil. The rotaryaction of the Moyno Down-HolePump outperforms reciprocatingpumps, its operating efficiency surpasses conventional electric submersible pumps, and it is idealfor gaseous formations because itcannot gas lock. Efficient, versatile,low-cost operation and long servicelife make the Moyno Down-HolePump the ideal choice for maximum profitability. Today, the progressingcavity pump in down-hole applica-tions is one of the fastest growingsegments of the artificial lift industry.

With over 60 years of proven experience in progressing cavitypump technology, R&M EnergySystems, a business unit of Robbins& Myers, Inc., is a name synonymouswith world-class leadership in pro-gressing cavity oilfield products.

As the original North Americanlicensee of the Moineau patent in1936, Robbins & Myers pioneeredthe progressing cavity pump princi-ple. Moyno pumps soon became the industry standard, successfullyproviding total pumping solutions in thousands of applications.

The Moyno Down-Hole Pump is aprogressing cavity pump specificallydesigned for crude oil extraction as

UNPARALLELEDROTOR/STATOR

QUALITY

In a Moyno down-hole pump, the rotor turns within the stator, forming cavities which progress from the suction

end to the discharge end of the pump, providing a relatively straight flow path and a constant, non-pulsating flow.

The continuous seal between the rotor and the stator helices keeps the fluid moving steadily, at a fixed rate directly

proportional to the rotational speed of the pump.

After years of successfully manufac-turing and marketing the progressing cavity concept in oilfield surfacepumping applications, Robbins &Myers achieved another first in 1955 successfully applying the progressingcavity principle to hydraulic motorapplications. The Moyno rotor/statorelement became the prime mover fora drill motor. This Robbins & Myerstechnological development providedan efficient, lasting, cost-competitivedrilling breakthrough, regardless ofdown-hole drilling conditions. Basedupon the success of the progressingcavity technology in oilfield surfacetransfer and drill motor componentapplications, the Moyno Down-HolePump has been applied successfullyin thousands of applications through-out the world.
