Pump type
SE 2500-180-10

The SE 2500-180-10 pump and the unit based on it are designed for pumping water in heating networks. Water must not contain solid particles larger than 0.2 mm and a concentration higher than 5 mg/l.

Pumps are manufactured in the UHL climatic version — intended for macroclimatic regions with moderate and cold climates, placement category 4 — operation in rooms (volumes) with artificially regulated climatic conditions according to GOST 15150-69.

APPLICATION OF THE SE 2500-180-10 NETWORK PUMP

The network pump belongs to a special group of power pumps, whose operation is characterized by fluctuations in the temperature of the supplied water over a wide range of flows. It is designed for pumping water with temperatures up to 120 °C in heating networks.

The SE 2500-180-10 network pump is driven by an asynchronous squirrel-cage rotor electric motor with a power of 1600 kW. The overall system efficiency (η) is 80 %.

MAIN REQUIREMENTS FOR THE DESIGN OF THE SE 2500-180-10 NETWORK PUMP:

  • High reliability and cost-effectiveness;
  • External tightness and absence of internal leaks at rotor and stator joint connections;
  • Long service life – average time to major overhaul at least 31,500 hours (with all maintenance requirements met);
  • Dynamic stability across the entire operating range;
  • Stable, continuously decreasing head characteristic to ensure stable operation in parallel operation;
  • Ease of assembly, disassembly, maintenance, and high serviceability in operational conditions.

CONSTRUCTION FEATURES OF THE SE 2500-180-10 NETWORK PUMP:

  • Horizontal design. Provides high vibration resistance, reduces shaft misalignment, and increases the service life of components;
  • Spiral type with a horizontal split along the pump axis. Ensures high maintainability, ease of technical maintenance and installation, and simple operation. The inlet and outlet nozzles are at the lower part of the casing, allowing pump assembly and disassembly without disconnecting pipelines;
  • Single-stage with a double-entry impeller, made of two halves;
  • Pump casing is a complex cast iron casting in two parts (pump cover and pump body) with semi-spiral inlet channels, two-turn spiral outlet, and chambers (thermal barriers) for supply and removal of cooling liquid to mechanical seals. Lower part of casing includes inlet and outlet nozzles, support legs, trough-shaped brackets for leakage collection, and bearing mounts. Support legs are positioned close to the pump axis to reduce misalignment from thermal expansion. A longitudinal keyway fixes the casing to the foundation frame for controlled thermal expansion;
  • Rotor is a separate assembly consisting of shaft, double-entry impeller in two halves, bushings, protective sleeves, bearings, and pump half-coupling. Axial movement of the impeller is fixed with bushings and nuts. Thermal expansion gaps are provided;
  • Rotor is axially balanced using the double-entry impeller;
  • Rotor supports are external sliding bearings. Drive side bearing handles radial loads; other side (sliding bearing + double-row angular contact ball bearing) handles radial and residual axial loads. Bearings are lubricated with ring (sump) oil; cooling coils are included for water cooling;
  • Mechanical seals are gland type with a seal ring. Seal cooling and prevention of air ingress is provided through chambers and pressure feed to the seal ring;
  • Torque is transmitted from motor to pump via a gear coupling.
