APPLICATION OF PUMP D 6300-27-3
The D 6300-27-3 pump belongs to the general-purpose pump group and is designed for pumping water and liquids with properties similar to water in terms of viscosity and chemical activity, at temperatures up to 85 °C, containing solid particles not exceeding 0.05% by mass, with a maximum particle size of 0.2 mm and microhardness not exceeding 6.5 MPa (650 kgf/mm²). It is widely used in various industries, agriculture, heating systems, municipal water supply, and more.
TECHNICAL CHARACTERISTICS
Nominal parameters of the D 6300-27-3 pump and its versions depend on the impeller outer diameter and rotational speed.
This parameter is crucial when designing the external network (piping and fittings) and selecting pumping equipment.
Dimensions and weight also depend on the impeller diameter and speed.
Drive: asynchronous three-phase squirrel-cage motors depending on impeller diameter and speed.
Efficiency (η): ranges from 82% to 86%.
DESIGN REQUIREMENTS
- High reliability and efficiency
- Extended operating range via impeller trimming and speed variation
- Long service life — average time before overhaul ≥ 45,000 hours (with proper maintenance)
- Dynamic stability across all operating modes
- Stable, continuously decreasing head curve for reliable parallel operation
- Correct selection of materials to ensure durability under operating conditions
- High standardization
- Ease of assembly, disassembly, maintenance, and repair
DESIGN FEATURES
- Horizontal design: high vibration resistance, reduced shaft misalignment, longer component life
- Volute type with horizontal split along pump axis: easy maintenance and installation; suction/discharge nozzles at the bottom allow assembly/disassembly without disconnecting pipes
- Single-stage, double-suction impeller
- Pump casing: complex cast iron structure (upper cover and lower casing) with semi-spiral inlet and spiral outlet channels; includes suction/discharge nozzles, support feet, leakage collection brackets, and bearing mounts
- Rotor assembly: shaft, impeller, inlet and protective sleeves, bearings, fasteners, half-coupling; axial positioning secured by sleeves and lock nuts
- Double-suction impeller: reduces axial load and improves cavitation performance
- Rotor bearings: external rolling bearings; drive side — single-row ball bearing (radial loads), opposite side — single-row ball bearing (radial and residual axial loads); grease-lubricated, air-cooled
- Sealing: stuffing box with hydraulic seal
- Torque transmission: flexible pin-and-bush coupling
MATERIAL SPECIFICATIONS
- Pump casing, bearing housings, impeller, inlet sleeves, sealing rings — cast iron СЧ200 (high strength and corrosion resistance)
- Shaft — carbon steel 45 (strength and wear resistance)
- Protective sleeves — stainless steel 30Х13 (durability and efficiency)
ADDITIONAL OPTIONS
- Higher-grade materials/coatings for flow parts to improve erosion resistance
- Optimized pump design for lower maintenance and longer service life
- Mechanical seals to reduce leakage and improve energy efficiency
- API 682-compliant seal chamber for interchangeability of mechanical seals
- Bearing units with liquid (sump) lubrication and oil cooling for longer life and energy efficiency
- Provision for sensors for monitoring temperature and vibration of bearings
- High-precision SKF rolling bearings for high-speed, low-noise, low-wear operation
- Flexible plate coupling between motor and pump to improve vibration performance
- VDS monitoring system: sensors for vibration, speed, and temperature, enabling predictive maintenance
