ROPE ROD COUPLING
It is designed to transmit translational (special version for transmission of reciprocating) motion to the rod pump plunger as a part of the pump rods, preventing rods turning back in deviated wells and in wells with excessive curvature set.
Description
Technical specifications
RELIEF VALVE
Area of application
- Fountain operation of wells;
- Pumping operation of wells with high gas factor;
- Combined well operation (start-up with a pump, after its shutdown - flowing operation).
Advantages
- Large flow area across the valves allows the pumping unit to operate both in normal mode and with a closed annulus;
- Allows the well to operate in gushing mode with downhole pumping equipment;
- Forms harmonic oscillations of bottomhole pressure and increases flow rate;
- In combination with ESP, it allows to operate wells with high gas factor (up to several thousand m³), engineering calculation is required.
Check ball valve
It is designed to reliably retain formation fluid in the tubing string when the electric centrifugal pump is stopped in order to prevent reverse rotation of the pump and to facilitate start-up after shutdown.
Technical specifications
- Connection thread: pumping and compressor pipes 48, 60, 73,89,114 to GOST 633-80
- Body material: steel 40XH2MA, other material as agreed with customer
- Seat and ball material: stellite

Option of valve with sludge trap
Feature
KNOCK-DOWN VALVE
It is designed for drainage of formation fluid from tubing and equalization of pressure in the interpipe space when the pump is lifted.
Technical specifications
- Connection thread: pumping and compressor pipes 48, 60, 73,89,114 to GOST 633-80
- Body material: steel 40XH2MA, other material as agreed with customer.
Description
SBC. 01 (Spring borehole centralizer)
- Versions are corrosion-resistant.
- Guarantees centering of items weighing up to 600 kg.
- Designed for centering of IECP(installation of an electric centrifugal pump)units of sizes 2A, 3, 4, 5, 5A.
WAC. 01(Well auxiliary centralizer)
- It is installed in the catcher journals of IECP(Installation of an electric centrifugal pump) of sizes 2A, 3, 4, 5, 5A.
- Designed to create a guaranteed clearance between the walls of the IECP unit and the casing string.
- Versions are corrosion-resistant.
CGF(Сentrifugal gravity filter)
Separation of solid particles from borehole fluid is performed by swirling and sharp change of direction of incoming flow (centrifugal separation), with sedimentation of cuttings under the action of gravitation into the collector.
To organize the supply, a collar-disconnector is installed.
When the collector is full, the discharge valve is automatically triggered and the sludge is poured into the sump.
If the accumulator is clogged, a by-pass valve is triggered to prevent the motor from overheating and to provide liquid supply to the pump inlet.
Separator is mounted in e/c 178,146, 140, 127; 114 and 96 (under construction).
Corrosion resistant design is available.
