Drilling Fluids Submersible Slurry Pump

Drilling mud process submersible slurry pump for drilling fluids centrifuge

Drilling mud process submersible slurry pump is widely used to feed fluids into decanter centrifuge. Such pump is rather compact and anti-abrasive. We call submersible slurry pump as maintenance-free pump. Besides used in oil drilling fluids process, submersible pump is widely used in HDD, trenchless, CBM mud recycling, too. At the job site, slurry pump set vertically in desilter tank for mud feeding into centrifuge 

For HDD and other mud system in civil construction, the slurry pump can be set over mud pit on a frame or support bar. Pump inlet port is submerged in pit or tank to transfer drilling mud into shaker. While in oil drilling mud system, the slurry pump will be set on desilter tank or compartment. If we have 2 sets of centrifuge, then 2 sets of slurry pump requested. For some users, they prefer the screw pump, since screw pump is progressive pump. But the submersible slurry pump is more durable and high-resistance to sand or cuttings in the drilling fluids. Moreover, the bearing and connection part between motor and pump body is above liquid level, so there is no need to maintain the pump. Higher efficiency and lower cost.

How to select the submersible slurry pump? For pump feeding centrifuge, we need to consider the centrifuge flow rate. For pump feeding shaker in the HDD mud system we should consider the whole mud system flow rate. And then the submersible length is another issue affect configuration or design. We can supply pump meet submersible depth up to 3m. How to achieve this? By extension pipe connected to input port.

Drilling fluids is transferred to desilter cones by centrifugal pump from the desander tank or compartment. Desilter cone is fed by desilter pump with fluids out of desander. Under pump pressure the fluids run into cones and flow with centrifugal force. Then the heavy particlas will deposit down and pushed out of cone drop in Apex. Particles larger than 15 microns will be separated out of drilling mud.

The submersible slurry pump is another kind of centrifugal pump. But it's more durable and strong than common pump. It can transfer many different kind of hard materials, including sand, cement, particles, shale and so on. So, it meets many requirements in different industries. The main structure including impeller, pump case, shaft, bearing, motor, supporting frame and so on.

Handling capacity is from 30m³/h to 120m³/h. The pump performance including flow rate, head, pressure. They will affect each other on the performance.
