Pump Features:- Gravel pump DTG, Construction of this pump is of single casing connected by means of clamp bands and wide wet passage. The wet parts are made of Ni hard and high chromium abrasion resistance alloys.
- The discharge direction of pump can be oriented in any direction of 360 degrees. This type of pump possesses the advantages of easy installation and operation, good performance of NPSH and abrasion resistance.
- Drive types includes V-belts driven, flexible coupling driven, gear box driven, hydraulic coupler driven, variable frequency driven, thyristor speed control etc.
- DTG gravel pump are designed for continuously handling the most difficult higher abrasive slurries which contain too big solids to be pumped by a common pump. They are suitable for delivering slurries in mining, explosive sludge in metal melting, grudging in dredger and course of river, and other fields. Type DTGH pumps are of high head ones.

Applications:
Sand and Gravel
The Heavy Duty Gravel Pump is designed for higher head duties such as cyclone feed, long distance pipelines and high static discharge heads.
The Heavy Duty Dredge Pump, is specifically designed for low head duties such as hopper dredging and barge loading.
With special impellers designed to prevent damage to the solids the Dredge pump is widely used for handling Sugar Beet and other vegetable products.
Low NPSH requirements and robust design make the Dredge and Gravel pumps suitable for applications on slurries with higher than normal temperatures.
Tunnelling
Severe space limitations and tough operating conditions are normal in tunnelling applications. The Gravel pump’s compact design and optional impact resistant cast steel components make it ideally suited for the varied subsoils and long tunnel lengths that require a pump capable of multi staging on a high flow, high pressure, often surging application.
