The pumping units designed into ISO 20ft containers used for special non-destructive hydrostatic pressure pipeline testing (NDT). Thanks to standardized ISO 20' container, the pumping unit can be easily moved to any locations, literally.
The pumping unit is determined for pumping water in gas pipelines, pipelines and other high-pressure pipelines for the purpose of their internal inspection and special hydrostatic pipeline testing (NDT). Innovative technology is a significant competitive advantage for our customers, allowing to carry out inspections even in pipelines, where it has not been possible so far. In cooperation with customer's inteligent pigging system, pumping unit allows to make inspections by methods that have not been physically feasible before. An important benefit of the device is its use for filling the pipeline with water for the pressure test. Its technical parameters make it possible to fill the pipes of large diameters or pipelines with extreme elevations much more quickly and efficiently.

AQ PUMPY was chance to built special tailor made pumping unit and fulfilled wish of our important customer, company engaged in inspections, repairs and other services of the long distance high pressure piping systems and pipelines.
Our devices consisted of two containers (ISO 20 feats). In each container is placed a high pressure centrifugal pump MARLY HPM 125 together with diesel motor Caterpillar CS 18 (power 571 kW) and to transmit the torque was used flexible coupling Omega.
Tailor made 2300 liters atmospheric fuel tank for long running, specially designed and built to maximize the interior space for using, maintaining and repairing the entire pumping unit. The electrical control valve DN 150 was used to control the flow of water from the control panel. Furthermore, deliveries contain complete wiring, fittings including suction baskets and 100 meters galvanized pipe.
The pumping unit was built into the ship's container mainly because of its long distance transport, the need for standardized dimensions and protection from damage and surrounding influences.
A six-cylinder turbocharged diesel engine with direct fuel injection and a cooling air cooler. The engine includes a control unit for smooth speed control. A pneumatically operated clutch is provided on the output shaft to enable pump and motor disconnection.
3. Pump MARLY HPM
Centrifugal high pressure pump MARLY (Italian manufacturer) with a flow rate of 3-900 m³ / h, pressure up to 100 bar.
The torque from the motor to the pump is transmitted by a flexible Omega coupling with a shield equipped with a speed sensor. An important parameter when choosing was vibration resistance.
The two fuel tanks are welded from a 3 mm thick steel sheet and are fixed to the floor of the transport container. The filler neck of both tanks is located at the front doors. Both tanks are interconnected and their total volume is 2300 liters, which allow to our customers long running even on inaccessible places. The upper walls of the tanks are covered by steel walking grids, which allow safe and nice operators' moving inside the container. The fuel tanks are equipped with a level sensor with output to the control panel. The inside of the tanks is treated with a special paint that is resistant to fuel oil.
Steel self supporting frame welded from U profiles. The frame is located on 4 pairs of silentblocks. The entire set was equipped with transport supports, which are used to transport the unit.
The suction branch of the pump is equipped with a sensor for pressure measurement - vacuum with output to the control panel. The suction branch connection is designed for installation into the VICTAULIC system. The suction branch diameter is DN 200.
The suction line of the unit is connected to the water level with a suction hose, ending with a suction cup with a non-return valve.
The delivery branch has DN125 and PN80 diaphragms. The return valve DN 125, PN 63 is located at the pump outlet. Immediately after the non-return valve is located a flowmeter with output to the control panel. Another element that needed to fit the delivery branch is a throttle valve with an actuator, which allows a smooth start and end of the pressure process. The valve position shows a PLC display located on the control panel, on which the valve can be opened and closed continuously, according to the required percentage. The pressure control on the discharge branch is monitored by two sensors located before and behind the throttle valve.
The output branch is made of 165.5x2.8 mm galvanized steel pipes PN 80. The length of the individual tubes is 6 m and the weight is about 70 kg. The VICTAULIC system is used to connect individual pipes. The length of the pipeline is 100 m and at the end there is a non-return valve for dewatering the system. Pipeline transport is secured by 9-pipe conveyors. Individual stacks can be stacked.
