How Much Do You Know About SHANGU® Roots Vacuum Pump for Vacuum Truck | MingTian Machinery Complete Solution

What Is a Vacuum Truck

A vacuum truck is a special‑purpose vehicle for material transportation, collection, storage and discharge of diverse dry and wet media including sewage, wastewater, mud, sludge, dust, soil, sand, stones, leaves, garbage, powder and granular materials as well as hazardous goods. It also supports non‑destructive digging and drilling mud recovery. Widely deployed across commercial, industrial, engineering and municipal projects worldwide. Made‑in‑China adopting US‑Japan reference‑grade technology.

A complete vacuum truck system consists of truck chassis, material tank body, vacuum & filtration assembly, high‑pressure water system and control system.

Typical Working Principle

  1. Evacuate the tank chamber to maintain stable vacuum pressure ranging from ‑60 kPa to ‑80 kPa.
  2. Material is sucked into the tank body by utilizing the pressure difference between atmospheric pressure and internal tank vacuum.

Main Types of Vacuum Pumps Used for Vacuum Trucks

Three mainstream blower types are applied for vacuum truck equipment: vane type, liquid‑ring type and tri‑lobe roots vacuum pump, all categorized as positive‑displacement exhaust blowers.

  • Vane‑type blowers: Suitable for small‑size vacuum trucks.
  • Liquid‑ring blowers: Suitable for small‑size vacuum trucks.
  • Tri‑lobe roots blowers: Preferred solution for medium‑duty and heavy‑duty large vacuum trucks.

Core Features of SHANGU® Tri‑Lobe Roots Vacuum Pump (Mingtian Machinery)

Two figure‑8 shaped lobes rotate in opposite directions, trapping and transferring gas medium without internal gas compression. Main housing adopts high‑strength cast iron material, optional anti‑corrosion surface treatment for harsh field working conditions.

  • Large airflow capacity: Maximum airflow reaches 460 m³/min.
  • High vacuum performance: Max achievable vacuum pressure: ‑78 kPa.
  • Oil‑free dry‑run operation, no oil contamination for conveyed medium, perfect for heavy‑duty mobile vacuum truck installations.
  • Low‑maintenance structure: Zero contact between lobes, casing and side wall plates. Extend overhaul intervals and lower onsite operating costs.

Wide Application Scenarios

  • Bulk cement pneumatic delivery tankers
  • Fly ash and coal powder pneumatic conveying
  • Grain bulk material conveying
  • Dust collection & industrial dust removal systems
  • Liquid waste & sewage sludge vacuum trucks, sucker trucks, vacuum trailers
  • Vacuum excavator, non‑destructive digging, hydro‑excavation projects
  • Mobile industrial high‑power vacuum cleaner equipment
