Description

The double casing radially split single stage cantilever pump offers high temperature resistance, abrasion resistance, and outstanding reliability. It is designed for efficient fluid transfer in severe working conditions, including those with solid particles and high temperatures. This pump minimizes maintenance costs and provides efficient, stable performance over long-term use.

Features:

  • High temperature resistance: Operates in environments up to 450°C, ideal for hot liquid transport in oil refining and petrochemical processes.
  • Abrasion resistance: Material and structural design enable strong abrasion resistance; suitable for fluids containing solid particles (e.g., coal slurry).
  • Long service life: Double-casing, heavy-duty design improves durability, reduces downtime and maintenance frequency even in harsh conditions.
  • Low maintenance costs: Durable design and accessible structure reduce maintenance and operating costs.

Main technical parameters:

  • Flow: Q = 8 to 853 m³/h
  • Head: H = 85 to 295 m
  • Operating temperature: ≤ 450°C
  • Drive power: approx. 400 kW

Structural features:

  • Double shell radial split design: Provides strength and durability, maintains stability under high temperature and pressure, enhances hydrodynamic performance, and simplifies maintenance.
  • Single-stage cantilever design: Concise structure efficiently supports high head and flow rate; cantilever shaft design excels in high-pressure fluid delivery.
  • Centerline installation: Improves stability and running accuracy for reliable long-term operation.
  • Suction port at the end, discharge port at the top: Ensures smooth fluid flow, reduces turbulence and energy loss, and boosts pump efficiency.

Main uses:

  • Refinery catalytic cracking unit (fractionation tower bottom pump): Handles high temperature, high pressure, and solid-containing media with mechanical strength and wear resistance for stable performance in catalytic cracking processes.
  • Petrochemical and coal chemical industry: Suited for installations with high temperature, particles, and viscosity; effective in complex chemical reactions and challenging fluid transfers, including coal slurries and other abrasive or viscous media.
