Types of Industrial Pumps:
Industrial pumps are normally divided into two basic categories:
- positive displacement pumps
- centrifugal or dynamic pumps
What are positive displacement pumps?
Positive displacement pumps use mechanical means for the fluid to flow and can vary the size of the fluid chamber because of a constant torque. They are designed to move fluid at a steady rate. They can handle viscous fluids more efficiently than kinetic pumps. However, at times they cannot achieve the high flow rates required for industrial applications. But when the low flow rates are preferred positive displacement pumps are definitely a better choice. They provide consistent flow and are not affected by pressure changes.
What are centrifugal pumps?
Centrifugal pumps demonstrate variable torque characteristics.These pumps provide momentum to the fluid by rotating impellers immersed in the fluid. This momentum leads to increase in either flow or pressure at the outlet of the pump. Centrifugal pumps can handle suspension very well and they do not require high maintenance.
|Vertical Multistage pumps – RVMS Series||Vertical Inline Pumps – RVI80 Series|
Inline centrifugal pumps are a special category of centrifugal pumps that can move a precise volume of liquid by maintaining a constant flow rate in a particular time frame. They are engineered in such a way so as to increase their efficiency and reduce load. These pumps are also designed to help reduce operating costs. There are two orientations available in the market: vertical and horizontal.
The vertical inline pump is similar to the end-suction pump in terms of the overall design. The only difference is that the casing has been designed such that the suction and discharge rims are in line with each other.In the end-suction pump type, this design is perpendicular. Vertical inline pumps are known for their compact and simple design.They are a cost-effective and popular option for small and medium sized applications.Vertical inline pumps are also growing in popularity in applications like chemical pumping applications, plumbing, HVAC etc.They are not used in solid-handling applications.
Advantages of Vertical Inline Pumps:
Vertical inline pumps render numerous advantages, some of which are mentioned below:
- They versatile enough to render applications, such as hot water, condenser water chilled water systems.
- They save floor space and reduce the amount of piping
- Flexible connectors are not required
- Foundation grouting is not needed
- Bearing frame assembly is not needed
- Coupling alignment is not needed
- Offers quick installation and mounts like a valve
- You can select multiple materials and customization according to your requirements
- The vertical shaft configuration promotes longer life of seal and bearings
- They have smaller spare parts inventory
What to know before buying a vertical inline pump?
When it comes to choosing a vertical inline pump, there are a number of factors that should be taken into account. You must first consider specific volume and pressure requirements of the application and the materials like clear water, fertilizer, oil and other chemicals that are being pumped. Also, check for horsepower requirements. When choosing the right pump for your operation, you must also pay attention to these additional attributes:
- optimum pump selection
- operational experiences
- vendor experiences
- application details
- pump model references
