As constituent part of Discharge manifold, the Adjustable choke perform the discharge control by the slow reduction of the pressure on free flow, determineted by gradually increasing the passage section.
The choke’s needle provides a variation of the passage section proportional to the displacement of the needle in the nozzle on the entire lenght of the stroke.
Access to the needle and the nozzle seat for replacement is possible by dismounting the plug along with all the parts assembled on it.
Locking the nozzle in a certain position of the needle is made by means of handle.

The cementing units are mobile units designed to perform cementing operations as well as other operations at the wells.
The cementing units are mounted on TATRA, ROMAN or KRAZ chassis trucks.
The cementing units are equipped with a high pressure triplex plunger pump that can develop power of 428 HP at 700 bar pressure under discontinuous operating conditions.
The power required to drive the triplex pump is supplied by the CATERPILLAR – C15 Tier 3 power unit, equipped with all air suction, control, cooling, discharging, lubrication systems.
The triplex pump is driven by CATERPILLAR TH35E81A transmission.
The gearbox is driven by a motor with cardan shaft driving the plunger pump by toothed coupling and the water pump by elastic coupling.

The cementing units are equipped with a measuring tank, divided into two equal compartments, protected against the corrosion.
For cementing operations, the cementing units are equipped with jet mixer with 3 nozzles supplied with water by a water pump. Water supply to the mixer is so conceived to provide parallel operation of one, two or all three nozzles of the mixer, as required, providing 100 to. blend/hour.
The controls of the Unit are centralized and may be actuated from the platform located around the control panel.
On the control panel are mounted instruments for checking the operation of the pluger pump and water pump, as well as instruments required to check the operation of the driving motor.
For checking the discharge pressure, the cementing units are equipped with pressure gauges with environment insulator and vibration dampener, mounted on the discharge collector of the pump.

The manifolds of unit provide the following functions:
– Triplex plunger pump suction from each compartment of the measuring tank, from the slurry cement sump or from other external source, on both sides of the unit.
– Triplex pump discharge towards the pumping line through the 2″ x 700 bar valve. Discharge on free line through the 2″ x 700 valve and ajustable nozzle. The adjustable nozzle permits slow reduction of the pressure on free flow line.
– Supply of measuring tank, independent for each compartment from external source.
– Water pump suction from each compartment of the measuring tank and water pump discharge towards the mixer cement.

To protect the entire hydraulic system against overpressure, the discharge manifold is provided with safety valve and water pump manifold is provided with spring valve.
