Casting Iron Oilfield Submersible Sludge Pump For Feeding Shale Shaker

Brief of submmersible slurry pump 

In oil and gas drilling, solids control system including many pumps. Slurry pump is one type among them. It is heavy-duty constructed centrifugal pump, which is able to deal tough and abrasive duties. The term slurry pump is considered a generic term, to separate from other type centrifugal pump, this one mainly use to intended for clear liquids. That is used as a feeding pump for the decanter centrifuge.

Why submersible slurry pump is popular with many solids control users? Submersible slurry pumps can be used to transfer fluids with big particles. It is single stage and single suction slurry pump. The pump shell and impeller no bearing, no shaft seal, which can pump medium with quantity of solid particles at lower maintenance cost

APYZ submersible slurry pump

The APYZ submersible slurry pump is a single-stage, single-suction cantilever structure. The hydraulic components of the pump are connected with a bearing seat, a supporting seat, and a connecting pipe. The liquid is discharged from the liquid outlet pipe. The impeller of the pump is a semi-open impeller. The inlet extension is equipped with agitating blades. The main feature of the pump is that the pump shaft at the submerged part has sufficient rigidity. There is no bearing between the impeller and the pump casing, and no shaft seal is used. medium. The length of the pump inserted into the liquid is between 800-2000, and a suction pipe can be equipped if necessary. The shaft seal adopts a larger pump to run in the liquid, without shaft seal, the transmission is installed on the motor support and support seat by a vertical motor, and is connected with the pump by a coupling.

Submersible slurry pump technical parameters

Submersible slurry pumps in solids control

Submersible slurry pumps have a very simple structure to ensure maximum performance, minimum energy consumption, long operating life and minimum maintenance. Many different designs can suit various transportation request in process application of grinding circuits, hydrocyclone feed and slurry transfer.

Vertical slurry pumps are widely used in many solids control systems. This kind of pump can be divided into two kinds, the tank pump and cantilever/sump pumps. The tank pump is considered as dry installed pumps and the sump is incorporated in the pump. It opens inlet to prevent air blocking and operate smoothly. The cantilever structure is single stage and suction with housing bearing, supporting the intermediate pipe connect it to pump’s hydraulic components. The water is exit out from the drainage. The impeller is semi-shrouded with the agitation vane on the extension. The main point on this pump is underwater shaft part contain enough rigidity, the impeller and pump should not have bearing and seal so it can be deliver greater medium of the solids cutting.

The submersible slurry pumps can be installed in mud tank or mud pit to transfer drilling fluid to shale shaker or centrifuge, so it can be in HDD jobsite. Very easy and convenient to operate.To provide users more convenience we can also provide control panel, cable connection between slurry pump motor and panel

Advantages of APYZ submersible slurry pump

1. This series of submersible slurry pumps adopt the internationally advanced solid-liquid two-phase flow theory and are designed according to the optimization principle. The geometry of the flow parts conforms to the flow state of the medium, reducing the local and along the way hydraulics such as vortex and impact. Loss, thereby reducing the wear of the over-current components, improving the hydraulic efficiency, and reducing the operating noise and vibration;

2. The flow parts of this series of pumps are made of high-hard alloy castings, and their materials have high abrasion resistance, corrosion resistance, and impact resistance, thereby increasing their life. In addition, this series of pumps adopts dynamic pressure reduction to ensure the slurry Not easy to leak.

How to select a submersible slurry pump?

Firstly, we need to check the centrifuge flow rate or treating capacity in oilfield mud sytstem. Usually we fit APYZ slurry pump driven by 10hp motor for a high speed centrifuge APGLW355X1258. Then, we need to consider the tank or pit depth. There will be initial design on slurry pump submerged length. We need to find out the professional supplier of such pump. It's important to centrifuge performance and whole mud system benefits, even whole drilling project

For the HDD mud recycling system, the slurry pump can be selected according to the shaker capacity. And then confirm the power of pump. The depth of such pump is very flexible. Even there is a pit deeps 3m, we can add an extended pipe on the pump inlet port

What are the popular slurry pump at AIPU?

There are different demand from various clients. However, the popular pumps including the AP50YZ50-30, AP80YZ80-30, and AP100YZ100-30. The difference including treating capacity, the motor power, the submerged depth. They are widely used in oilfield mud process and HDD mud recycling system.

The scope of application of the submersible slurry pump

The submerged slurry pump produced by our company is mainly used in oil drilling mud systems. The device can also be used in environmental protection, municipal engineering, thermal power plants, gas coking plants, oil refineries, steel mills, mining, paper industry, cement plants, Food factories, printing and dyeing industries suck concentrated liquid, heavy oil, oil residue, dirty liquid, mud, mortar, quicksand and flowing sludge from urban sewage channels, as well as fluids containing mud, sand, and corrosive liquids.

The submerged slurry pump is a single-stage single-suction cantilever structure, and the impeller is semi-open. There are no bearings between the impeller and pump shells of the hydraulic slurry pump, and no shaft seal is used. It is maintenance-free. Generally, it can transport media with a large concentration and solid particles. The suction volume is large. The flow parts are made of wear-resistant alloys. .
