Centrifugal Pump Basics: Types of Impellers. In this edition of the Centrifugal Pump Minute, James Farley, Senior Director of Product Management for Griswold, takes a look at the different types of centrifugal pump impellers. Additionally, James discusses how the impeller impacts a pump’s hydraulic performance. Learn More
Classifications of Pumps - Engineering ToolBox
Pumps are in general classified as Centrifugal Pumps (or Roto-dynamic pumps) and Positive Displacement Pumps. Centrifugal Pumps (Roto-dynamic pumps) The centrifugal or roto-dynamic pump produce a head and a flow by increasing the velocity of the liquid through the machine with the help of the rotating vane impeller.
Different Types of Pumps: Working & Their Applications
Dynamic pumps are classified into different types but some of them are discussed below like Centrifugal, Vertical centrifugal, Horizontal centrifugal, Submersible, and Fire hydrant systems. 1). Centrifugal Pumps. These types of pumps are most commonly used worldwide. The working is very simple, described well and carefully tested.
Top Cause of Single-Phase Motor Malfunctions | Fluke
May 09, 2021· Most problems with single-phase motors involve the centrifugal switch, thermal switch, or capacitor(s). If the problem is in the centrifugal switch, thermal switch, or capacitor, the motor is usually serviced and repaired. However, if the motor is more than 10 years old and less than 1 HP, the motor is usually replaced. If the motor is less than 1/8 HP, it is almost always replaced.
Motor Starting Basics | Pumps & Systems
Jun 19, 2019· Questions about starting electric motors are common. Motor starting problems resulting from these questions can be costly and confusing, leading to production delays and sometimes catastrophic motor failure. This article will briefly explore some of the most common questions about the direct online (DOL) starting of squirrel cage induction motors.
Types of Water Pumps for Construction
Jun 25, 2019· A centrifugal water pump uses a rotating impeller to move water into the pump and pressurize the discharge flow. Centrifugal water pumps come in several different types, including standard, trash, and submersible models. All liquids can be pumped using centrifugal water pumps, even those with low viscosity.
1-1. Diaphragm Pump: What Is a Diaphragm Pump? | Basics ...
Based on the above working principle, diaphragm pumps have the following characteristics. 1. Liquid Flows With Pulsation. Because of its operating principle, liquid flows intermittently due to the alternation of suction and discharge. This is called pulsation, which makes diaphragm pumps fundamentally different from centrifugal pumps.
