 difference between reciprocating pump and centrifugal pump|api 675 vs 674 I have a query regarding one of the vessel’s sea water ballast pumps. Brief details of the pump: - Electrically driven centrifugal ballast pump - Speed 1180 rpm - NPSHr 4.3 mlc - Rated Capacity 2800 m3/hr - The pump is regulated by throttling the discharge valve. When operating the pump I have observed the following:

A lock ( lock ) or difference between reciprocating pump and centrifugal pump|api 675 vs 674 Maximum Permissible Viscosity Of Fluid For Centrifugal Pumps - posted in Industrial Professionals: dear all I have a latex (XSBR) with max viscosity of 600 mPa.s. . As a general "rule of thumb", I have always used 300 cP as the limit for centrifugal pumps. Although centrifugal pumps can be used with fluids of higher viscosities, they become .

difference between reciprocating pump and centrifugal pump|api 675 vs 674 : mfg It is a positive displacement type pump where a certain volume of liquid is entered in closed volume and discharged using pressure to the … See more The diffusers made it thru final machining and we were testing the pumps. Everything was right during testing except flow rate, approximately 50%. We pulled that damn pump 3 times and checked clearances, dimensions, lift ect. Finally we had the pump sitting next to an older pump and the WELDER goes those castings are different. Fun times.

Most centrifugal pumps have an arrow on the pump body or the motor, which shows the rotation direction. If your pump motor rotates in the opposite direction to that on the pump, reverse any two wires in the supply to change the rotation direction – and get your pump working the way it’s meant to. 2.

When we talk about pumps, the first definition that comes to mind is that it delivers water or other liquid from one place to another place. A pump is a device that is used for lifting the liquid from the ground surface and delivering it to the topmost upper surface. The pump converts mechanical energy into hydraulic energy to move the fluid. There are various types of pumps available in the market, each designed for specific applications. Two common types of pumps are reciprocating pumps and centrifugal pumps. In this article, we will explore the differences between reciprocating pumps and centrifugal pumps.

Positive Displacement Pumps Diagram

Positive displacement pumps are a type of pump that operates by trapping a fixed amount of fluid and then forcing that trapped volume into the discharge pipe. This creates a constant flow regardless of changes in pressure. The diagram of a positive displacement pump shows how the fluid is trapped and then forced out in a cyclical manner.

Centrifugal Pump vs. Reciprocating Pump

One of the main differences between centrifugal pumps and reciprocating pumps is their operating principle. Centrifugal pumps work on the principle of centrifugal force, where a rotating impeller imparts kinetic energy to the fluid, causing it to move radially outward. On the other hand, reciprocating pumps operate by using a piston or diaphragm to create a back-and-forth motion, which results in the movement of the fluid.

Indicator Diagram of Reciprocating Pump

The indicator diagram of a reciprocating pump shows the pressure-volume relationship during the operation of the pump. It helps in analyzing the performance of the pump and identifying any inefficiencies or losses in the system.

Single Acting Reciprocating Pump Working

A single-acting reciprocating pump works by using a piston that moves back and forth in a cylinder. During the suction stroke, the piston moves away from the valve, creating a low-pressure area that allows the fluid to enter the cylinder. In the discharge stroke, the piston moves towards the valve, forcing the fluid out of the cylinder.

Characteristic Curve of Reciprocating Pump

The characteristic curve of a reciprocating pump shows the relationship between the flow rate and the head developed by the pump. It helps in determining the operating point of the pump and its efficiency under different conditions.

Characteristics of Reciprocating Pump

Reciprocating pumps have several characteristics that make them suitable for certain applications. They are known for their high efficiency, ability to handle high pressures, and precise flow control. However, they can be more complex and require more maintenance compared to centrifugal pumps.

API 675 vs. 674

API 675 and API 674 are standards set by the American Petroleum Institute (API) for reciprocating pumps used in the oil and gas industry. API 675 covers metering pumps, while API 674 covers reciprocating pumps for general service. These standards ensure that the pumps meet specific requirements for reliability and performance.
