2. Sludge vacuum pump

GN Solids Control vacuum pump is a pneumatic pump with air as power source, which can be used to transport mine tailings, drilling waste, industrial slurry, chemical powder, construction aggregate, oil sludge, kitchen waste and other materials.

In the material conveying work, the screw conveyor is usually used for transmission, but because of the short conveying distance and high cost, the long-distance conveying demand cannot be well satisfied. The GN solid vacuum pump can reach a suction distance of 50 meters and a discharge distance of 1000 meters for clean water. It is of great significance for long-distance transportation.

The reason why GN Solids Control vacuum pump can have good effect and long head for solid conveying is because it can form high negative and positive pressure. GN Solids Control specially designed two types of vacuum pump rotary unloading device and vacuum pump buffer funnel to relieve pressure and prevent the impact in the process of discharging materials. So as to meet the requirements of customers.

This time, the sludge vacuum pump was supplied to a well-known environmental protection customer for material transportation, and a decanter centrifuge was used for solid-liquid separation, so as to meet the process requirements of the environmental protection company.

If you have any needs in this regard, you are welcome to contact GN Solids Control.

As a professional solid-liquid separation equipment manufacturer, after more than 10 years of continuous research and development and innovation. GN Solids Control has become a well-known brand in the solids control equipment industry at home and abroad. GN Solids Control provides different mud purification systems and devices for different customers every year to meet the requirements of customers.

This week, GN Solids Control delivered 4 sets of pipe jacking mud purification units to Southeast Asian customers, including 2 sets of GNMS-15000D and 2 sets of GNMS-1000D systems, which can handle up to 1500 GPM and 1000 GPM depending on on-site treatment conditions. Its main configuration is as follows:

1. GNMS-1500D trenchless mud purification device

The GNMS-1500D trenchless mud purification unit consists of a GNZS707 double-layer shale shaker and two 16-inch desander cyclones, a compact mud tank and a centrifugal pump. The mud first passes through the lower coarse screen of the GNZS707 vibrating screen, and the separated solid phase is directly discharged from the vibrating screen. The liquid phase is collected by the mud tank below, and transported to the de-sanding cyclone by the centrifugal sand pump, and the liquid-phase mud is recovered and reused through the separation of the de-sanding cyclone. The solid phase falls to the upper layer of the vibrating screen for fine screening, and part of the mud is recovered again for the next cycle. The solid phase is directly discharged from the upper layer of the vibrating screen.

2. GNMS-1000D trenchless mud purification device

It is similar to GNMS-1500D trenchless mud purification device, GNMS-1000D consists of a GNZS705 double-layer vibrating screen and two 10-inch desander cyclones, compact mud tank, centrifugal sand pump. Its working principle is the same as GNMS-1500D.
