SLY400 directional and reverse circulation construction and water well drilling rig is designed by our engineers; it is a rotary drilling rig.The main transmit, transmission power, gearbox, sets of windlass, mud pump, sewage pump,mast are setup on the chassis.
SLY400 small water well drilling rig has directional and reverse circulation pump, it adopts slurry as the washing fluid, and the directional circulation drilling and reverse circulation drilling can be switched by changing mud pump and sewage pump. We can set up the spare electric engine and clutch implement according to client's requirement, so that the rig can work with diesel engine or electric engine. We can set up an electric generator (MF) according to client's requirement, which can provide lighting in night
We can set up the hydraulic adding pressure implement, so it has a high efficiency when the rig drill on mud rock and weathering formation through using the adding pressure implement.
The master driving of rig is mechanical. Distribute box, sewage pump, master driving clutch system are air operated. The assistant pipes have two types: flanged and screw linked.
SLY400 small water well drilling rig has a high efficiency because of having larger torque, it is suitable for deep water well, construction, building, bridge foundation, port, dam and so on, it is popular with the domestic and foreign clients.

SLY400-T small water well drilling rig is lightweight, efficient, multi-purpose drilling equipment, which can use air, foam or mud rotary for percussive drilling according to different textures.
This kind of small water well drilling rig is widely used in industrial and agricultural water conservancy projects, such as drilling wells, testing wells or other exploration boreholes, in particular, in drilling hole for geothermal heating. It can also meet the engineering basis for reinforcement, loose gravel drilling rock formation connected with a variety of engineering requirements.
