Construction of nitrogen and oxygen production plants

Professional design, supply, installation, and commissioning of comprehensive fluid pumping systems for drinking and process water supply, wastewater disposal, fire suppression, and industrial processes.

Reliable and uninterrupted operation of pumping equipment is critically important for municipal utilities, industrial enterprises, agricultural complexes, and infrastructure facilities. LLC «Dalgakiran Compressor Ukraine» implements comprehensive projects for the construction, reconstruction, and automation of pumping stations of any purpose and capacity «turnkey».

We assume full responsibility for each stage — from calculating hydraulic parameters and selecting pump types to construction and installation works, connecting control cabinet systems with variable frequency control, commissioning, and further service maintenance.

Why is it worth ordering the construction of a pumping station «turnkey»?

A single contractor and responsibility: One contractor is responsible for the entire scope of work — from engineering and hydraulic calculations to commissioning the facility.
Maximum energy efficiency: The use of frequency converters (FC) and high-efficiency electric motors makes it possible to reduce electricity consumption by up to 30–50%.
Protection against water hammer and accidents: The implementation of soft start systems, frequency control, and safety valves extends the service life of pipelines and equipment.
Automated control and dispatching: The station can operate in a fully autonomous mode with data transmission to the operator’s console or mobile devices.

Stages of construction of pumping stations «turnkey»

1. Hydraulic audit and calculation of pumping parameters>

The first stage is to determine the actual or calculated needs of the facility for fluid supply and the required pressure.

For operating enterprises and networks (modernization): An audit of the existing pumping station is carried out, the actual flow rate (Q, m³/h), head (H, m), electricity consumption, condition of pipelines and shut-off valves are measured, and leaks and peak load modes are identified.
For new facilities (construction from scratch): The required hydraulic parameters are calculated based on the requirements of the technological process, general plan, number of floors, fire safety standards, or volumes of wastewater.

Stage result: Determination of the types and number of pumping units (operating and standby), their operating scheme (parallel/series), the required head, flow rate, and requirements for the quality and composition of the fluid (clean water, drainage, sewage, or aggressive media).

2. Feasibility study (FS) and efficiency calculation

At this stage, various equipment options and control schemes are compared to achieve the lowest operating costs.

We calculate:

Projected reduction in electricity consumption through the implementation of a variable frequency drive (VFD);
Reduction in service and repair costs by eliminating water hammer;
Reduction of water losses and elimination of emergency shutdowns;
Investment payback period (ROI) and the overall economic effect of modernization or construction.

Stage result: A substantiated feasibility study comparing capital and operating costs and the investment payback period.

3. Development of design documentation

The third stage covers the development of sets of design and cost estimate documentation in accordance with the current construction, technological, and environmental standards of Ukraine.

The project includes the following sections:

Technological part (TP): Selection of pumps, intake and pressure manifolds, shut-off and control valves, check valves, filters, and measuring instruments;
Construction part (CP/RC): Foundations for pumping units, underground tanks, receiving tanks (for SPS), station premises;
Electrical part and automation (EP, AIT): Power supply, pump control cabinets (with FCs or soft starters), pressure, level and flow sensors, grounding, and lightning protection;
Dispatching and telemetry: Data transmission via Modbus, Profibus, GSM/GPRS protocols to the upper control level.

Stage result: An approved project that has passed the necessary approvals, a completed equipment specification, and a cost estimate for the works.

4. Construction works and site preparation

The fourth stage provides for the performance of general construction and preparatory works directly at the facility.

Capital construction or reconstruction of premises: Construction or repair of the station building, installation of vibration-isolated foundations for pumps, preparation of drainage pits, laying of cable ducts and technological openings.
Sewage pumping stations (SPS) and underground tanks: Earthworks, installation of reinforced concrete or fiberglass tanks/certified SPS housings, waterproofing works, and preparation of receiving chambers.

Stage result: A completed construction part that meets the technical requirements for the installation of heavy pumping and hydraulic equipment.

5. Supply, installation, and engineering piping

The fifth stage includes prompt delivery of pumping units, control cabinets, pipelines and fittings, their positioning and installation.

Our specialists perform:

Installation of end-suction, borehole, submersible, multistage, or self-priming pumps;
Installation of pressure and suction manifolds made of stainless steel, galvanized steel, or modern polymer materials;
Installation of butterfly valves, check valves, gate valves, vibration-damping inserts (compensators), and strainers;
Installation of control cabinets, measuring instruments (pressure gauges, flow meters, dry-run sensors), and connection of power and control cables.

Stage result: A fully installed pumping station tested for hydraulic strength, tightness of connections, and compliance with the design documentation.

6. Commissioning works, setup, and personnel training

The final stage — comprehensive testing and commissioning of the pumping station.

Engineers of «Dalgakiran Compressor Ukraine» carry out:

Flushing and pressure testing of hydraulic lines;
Setup of frequency converters, calibration of pressure and level sensors;
Testing of automatic switching algorithms «duty/standby pump», soft start and stop;
Checking the operation of protection systems (against dry running, overload, phase imbalance, leaks);
Testing of the pumping station in all operating and peak load modes.

Personnel training: We provide detailed instruction to the customer’s technical personnel on the rules for safe operation of pumping equipment, operation of control cabinets, scheduled maintenance, and actions in the event of emergency situations.

Stage result: Signing of the commissioning certificate, transfer of a set of as-built documentation, and placing the facility under warranty service.
