Why is compact equipment important for pressure vacuum tankers?

High-specification pressure vacuum tankers can have restricted installation space. The compact designs of the XK18 and HeliFlow allow both machines to be installed within the limited space envelope described in the case study.

What operating conditions can the equipment handle?

In this application, the XK18 and HeliFlow operate in demanding, dusty conditions where continuous loading and unloading takes place.

Which industries use these dry bulk transport vehicles?

Applications identified in the case study include metallurgy, chemical engineering, petroleum, building materials and coal dust transfer.

Pressure Vacuum Tanker Equipment for Dry Bulk

Q: What is the XK18 screw compressor used for?

The XK18 is an onboard screw compressor. Its large air volume helps improve the efficiency of the suction and discharge process in this pressure vacuum tanker application.

Overview

Pressure vacuum tankers used for industrial dust and dry bulk materials require reliable suction and discharge equipment that can operate continuously in demanding, dusty conditions. For Wuhan Gaohua, compact installation was also critical because of the limited space available on its high-specification pressure vacuum tankers.Working with Gardner Denver China, Wuhan Gaohua uses the XK18 screw compressor together with a HeliFlow vacuum pump to support hermetic suction and pressure discharge operations. The combination is designed to improve the efficiency of the suction and discharge process while fitting within a restricted vehicle installation envelope.

Challenge: Efficient Suction and Discharge in Demanding Conditions

Wuhan Gaohua manufactures suction and pressure vehicles for bulk transport applications in industries including metallurgy, chemical engineering, petroleum, building materials and coal dust transfer.These vehicles perform hermetic suction and pressure discharge operations and must work in particularly challenging environments. The case study highlights two important requirements:

Continuous loading and unloading in dusty conditions
Very limited installation space on high-specification pressure vacuum tankers

The application therefore required equipment capable of supporting the necessary suction and discharge performance while remaining compact enough for the available vehicle space.

Solution: XK18 Screw Compressor and HeliFlow Vacuum Pump

The solution combines two Gardner Denver technologies:

XK18 screw compressor for the pressure discharge process
HeliFlow vacuum pump for suction operations

The compact design of both machines allows the compressor and vacuum pump to be installed in the restricted space available on the pressure vacuum tanker.The large air volume of the XK18 onboard compressor supports efficient discharge performance, while the HeliFlow provides the vacuum required for suction. Together, the technologies provide a combined solution for pressure vacuum vehicles performing repeated loading and unloading operations.
