Centrifugal Pump APSB 6*5-14 37Kw With ATEX Certificate 50/60HZ

Centrifugal pump is widely used in the solids control systems of oil and gas drilling. Centrifugal pump is worked as the feeding pump to drilling mud cleaner, drilling mud desander, drilling mud desilter, as well as an important part of jet mud mixer. No matter for oil and gas drilling, or water drilling, CBM, or piling. The solids control system needs the centrifugal pump to be power or energy supply of fluid circulation.

Centrifugal pump is made of the pump head, explosion-proof motor, and base. Pump heads there are 8x6, 6x5, and 3x2 for options. Motor including explosion-proof and non-explosion-proof. And the electrical parts can be ATEX certified against customers' requirements.

How centrifugal pump works

Applying classical mechanics theory, assuming viscosity of the liquid equal 0 and no energy loss for the work of energy transferring from the impeller to the streamlines which means that, all separate flow will be uniforms (this approximation of physical reality to get the simpler as solid-state mechanism than a hydraulic mechanism
General explanation: Like most pumps, centrifugal pumps convert rotational energy, often from a motor, to energy in a moving fluid. A portion of the energy goes into the kinetic energy of the fluid. Fluid enters axially through the eye of the casing, is caught up in the impeller blades, and is whirled tangentially and radially outward until it leaves through all circumferential parts of the impeller into the diffuser part of the casing. The fluid gains both velocity and pressure while passing through the impeller. The doughnut-shaped diffuser, or scroll, a section of the casing decelerates the flow and further increases the pressure
In the drilling fluid solids control system, centrifugal pumps are used as a transfer pump. Mainly pump drilling fluid to desander hydrocyclone, desilter hydrocyclone. They also are combined with mud hopper to be jet mud mixer or mud mixing pump. Pumps work as power transition tools.

Centrifugal pump types in solids control

Drilling fluid solids control requests many centrifugal pumps to be fit on mud tanks. According to function, we call centrifugal pumps sand pumps, submersible slurry pumps, shear pumps, charging pumps, etc. They are defined for their different functions, but their working principle is the same
Usually, in drilling fluid solids control there are horizontal centrifugal pumps and vertical centrifugal pumps. The difference is motor installation direction and pump feed inlet position.
To select either of the installation ways we need to consider the actual operation condition and general space. Presently, except installation way, there are different types of pumps on the seal. Mechanically sealed pumps are more popular since the stable performance and reliable quality

Selection of centrifugal pump:

First, determine how much capacity the centrifugal sand pump is, or need the capacity which is equipped with a centrifugal pump. Generally, choose centrifugal pump capacity should be a little larger than the matched equipment. There is a valve in the centrifugal pump outlet to regulate the flow required.
Ensure how much lift do centrifugal pump need. Choose a big lift centrifugal pump, because the loss of pipeline is very large.
If centrifugal pumps supply mud to the desander and desilter, then choose the larger capacity centrifugal pump. Because the desander and desilter require very strict and keen for the pressure. If the choice of centrifugal pump capacity is small to supply the desander and desilter, the pressure is insufficient, thus affecting the desander and desilter working effect.
