Key Engineering Solutions

Pumps and Pump Units

Selection based on load, torque, gear ratio and actual operating mode.

Typical issues we prevent:

incorrectly selected torque;
gearbox overload and accelerated wear;
reduced service life due to incorrect gear ratio selection.

Parameters we take into account:

load and starting torque;
rotational speed and operating cycle;
operating conditions;
service life and maintenance requirements.

We offer cost-effective alternatives to European manufacturers without compromising operational performance.

Drives and Gearboxes

Request engineering selection

Typical issues we prevent:

overheating of units;
unstable temperature control;
insufficient heating capacity.

Parameters we take into account:

temperature regime;
heat losses and required power;
operating medium;
accuracy and stability requirements.

We select heating and thermal stabilization systems for technological processes.

Heating and Temperature Control

We select filtration systems to protect equipment and ensure stable product quality.

Filtration

Request engineering selection

Typical problems we prevent:

premature wear and pump failure;
unstable flow and insufficient head;
equipment failure due to incorrect selection for the pumped medium.

Parameters we take into account:

flow rate and pressure;
viscosity and temperature of the medium;
suction conditions;
material of the wetted parts.

Selection based on flow rate, head, viscosity and suction conditions.

Request engineering selection

Typical problems we prevent:

premature equipment wear caused by contamination;
pressure drop and unstable system operation;
frequent filter element replacement and increased operating costs.

Parameters we take into account:

type and concentration of contaminants;
filtration class (degree of filtration);
flow rate and operating pressure;
operating medium and temperature conditions.

Case 1.

Heated hose for co-extruder (sanctioned component)

Task:
Ensure co-extruder heating and replace a sanctioned component without stopping the production line.

Initial parameters:
Co-extruder temperature regime, connection type, compatibility requirements.

Problem:
Original part unavailable due to sanctions; alternative suppliers offered high prices and long lead times.

What we did:
Selected a technically compatible heating hose, fixed the cost, approved the solution with the customer’s technologist and organized delivery with installation.

Result:
Part found in 2 days, cost 4 times lower than competitors. Delivery and installation completed within 2 weeks, downtime prevented.

Case 2.

Spare parts for extrusion machine

Task:
Ensure delivery of spare parts for an extrusion machine under limited timeframes and high supplier prices.

Initial parameters:
Extrusion equipment model, spare part specifications, compatibility and service life requirements.

Problem:
Long delivery times and high costs from alternative suppliers; lack of confidence in result.

What we did:
Analyzed compatible alternatives, agreed on trial delivery, ensured compliance control.

Result:
First batch delivered in 3 weeks. Parts confirmed performance, customer continued long-term cooperation.

Case 3.

Electrical kit for injection molding machines

Task:
Select and supply an electrical kit for injection molding machines with strict commissioning deadlines.

Initial parameters:
Machine configuration, electrical component requirements, approved delivery terms.

Problem:
Risk of launch delays using standard logistics schemes.

What we did:
Quickly selected components, agreed supply composition and optimized logistics.

Result:
Components selected within 2 hours, delivery completed 2.5 weeks earlier than planned, without additional cost.
