What is a VS6 pump?
The pump type VBR (VS6) is a double casing single or multistage design incorporating single or multi radial vane impellers with front and rear wear rings, each impeller has its own diffuser. VBR vertical shaft pumps feature a barrel (suction can) and are suitable for dry or wet well uses.
What is vertical suspended pump?
Vertically suspended pumps Vertically suspended (VS) pumps include the subgroups wet-pit and vertically suspended diffuser pump (VS1), which discharges liquid through the pump column. Another type is a volute version of the vertically suspended pump (VS2).
What is a vertical can pump?
Vertical turbine pumps are centrifugal pumps specially designed to move water from an underground well or reservoir. They’re also known a deep well turbine pumps or a line shaft turbine pumps. Vertical turbine pumps work when water enters the pump through a bell-shaped part at the bottom called the suction bell.
Where vertical pump is used?
Vertical pumps are often used in plants and locations where there are space or weight restrictions. Another advantage of vertical pumps is that the alignment between the driver, usually an electric motor, and pump is easier to maintain than many horizontal pumps.
What is OH2 pump?
The pump type HZC ( OH2 ) is a series of horizontal overhung centerline mounted, single stage, single suction heavy duty centrifugal pumps with diffuser and volute design casings.
What is vertical centrifugal pump?
Vertical centrifugal pumps are also referred to as cantilever pumps. They utilize a unique shaft and bearing support configuration that allows the volute to hang in the sump while the bearings are outside the sump. This style of pump uses no stuffing box to seal the shaft but instead utilizes a “throttle bushing”.
Why do we use vertical pumps?
When you have a restricted surface area and need a pump that takes up a much smaller footprint, vertical centrifugal pumps will definitely take up less floor space. They are well-suited for liquids with high temperatures and pressures, and the NPSH can be altered to handle a wider range of applications.
What type of pump is a vertical pump?
centrifugal pump
A vertical turbine pump, also known as a vertical pump or lineshaft pump, is a centrifugal pump that transports water from deep underground. A common type of vertical turbine pump is a submersible pump, which is situated entirely underwater. With a submersible pump, the motor is located at the bottom of the system.
What is the difference between vertical and horizontal pump?
The first and most obvious difference is the orientation of the shaft. A horizontal centrifugal pump will have its shaft placed horizontally, typically between the bearings or overhung. Meanwhile, a vertical centrifugal pump has a shaft that is oriented vertically. The design of the shaft is radial split and overhang.
How do vertical pumps work?
Vertical turbine pumps work when water enters the pump at the bottom through a bell-shaped part called the suction bell. From there it moves into the first stage impeller, which raises the water’s velocity. At the surface is the pump discharge head, which allows the flow to change direction, toward the discharge pipe.
Is vertical or horizontal pump better?
On the positive side, horizontal centrifugal pumps are easier to install and maintain with internal parts that are simple to access. In general, the working temperature and pressure are lower in horizontal pumps when compared to vertical alternatives.
What is centerline mounted pump?
Most ANSI pumps are designed with foot mounted casings. Centerline support simply means that the pump casing is supported at the shaft centerline. This allows thermal expansion growth of the casing to be symmetric from the shaft centerline outwards.
What kind of vertical can pump does Sulzer use?
VS6 vertical can pump. The SJD (API) are ISO 13709/API 610 Type VS1 and VS6 pumps whose design has evolved from many years of experience. They utilize Sulzer’s low Net Positive Suction Head (NPSH) 1st stage, followed by unique high head per stage series hydraulics, to minimize the number of stages required.
What kind of hydraulics does a VS6 vertical can pump use?
The SJD (API) are ISO 13709/API 610 Type VS1 and VS6 pumps whose design has evolved from many years of experience. They utilize Sulzer’s low Net Positive Suction Head (NPSH) 1st stage, followed by unique high head per stage series hydraulics, to minimize the number of stages required.
Which is the first stage of the Sulzer process pump?
Sulzer’s low Net Positive Suction Head (NPSH) 1st stage, followed by unique high head per stage series hydraulics, minimize the number of stages required, reducing pump length and contractor’s associated civil costs.
What can a Sulzer multistage pump be used for?
For the past 30 years, Sulzer multistage pumps have been used to pump compressible, dense phase ethylene and CO2 at normal and supercritical pressures. Compressible performance prediction, acoustic studies, and, lateral analysis, are all part of service provided by Sulzer engineers for such rigorous applications.
