Unveiling the Inner Workings of Flygt Drainage Pumps


When it comes to efficient wastewater management, drainage pumps play a pivotal role for a variety of industries up and down the UK and overseas. These unsung heroes quietly work beneath the surface, ensuring that wastewater is effectively transported and managed. But have you ever wondered how these pumps operate? Or thought about how these applications work? Let’s dive into the mechanics of Flygt drainage pumps and understand how they work their magic.


The Basics of Drainage Pumps

Before we explore the specifics of Flygt pumps, let’s grasp the fundamental principles of drainage pumps.

  1. Inlet: Drainage pumps are strategically placed at low points or collection areas, where wastewater naturally flows to or accumulates.
  2. Impeller: At the heart of a drainage pump is the impeller—a rotating component with vanes or blades. The impeller’s job is to draw in wastewater and create a flow of liquid.
  3. Casing: The impeller is housed in a casing or chamber. As it spins, it generates a centrifugal force that propels wastewater outward.
  4. Outlet: The pumped wastewater or dirty water is pushed through an outlet or discharge pipe to its intended destination, such as a treatment facility or a drainage system.

Our large drainage pump fleet ranges in size from small 0.4kW units right the way up to the 90kW 2400 Flygt pump- the largest drainage pump available and part of the popular Flygt Bibo range of pumps.

Drainage Pumps come in many different shapes and sizes, but they all share a common function: they are able to move water from one area to another. We stock drainage pumps from a variety of the world’s most highly regarded manufacturers, including Tsurumi and Flygt.

Submersible drainage pumps are excellent for pumping water and dirty water mixed with light abrasives. The pump design enables convenient transport, handling and installation, all of which can be undertaken by the expert Pump Supplies team. The Bibo runs right through the heart of our drainage fleet, being widely used in harsh applications worldwide because of their wear resistance, longevity and reliability.


Flygt Drainage Pumps: The Inside Story

Now that we understand the basic principles and their uses, let’s take a closer look at Flygt drainage pumps.

  1. Submersible Design

Flygt drainage pumps are often submersible, meaning they are installed underwater. This design choice has several advantages. It keeps the pump cool, reduces noise, and eliminates the need for priming. The submersible nature of Flygt pumps makes them highly efficient and reliable.

  1. Impeller Innovation

Flygt is renowned for its innovative impeller design. The Flygt pump has a hard iron impeller which is also trade marked – Specially designed impeller with high chromium content for superb wear resistance (60 HRC).

  1. Seal Solutions

Seal failure is a common issue in drainage pumps. Flygt addresses this challenge with its patented Spin out feature which is trade marked; Protects seal by expelling abrasive particles from the seal chamber, extending service life.

  1. Variable Speed Control

Flygt drainage pumps can be provided with variable speed control drives. This allows you to adjust the pump’s speed to match the flow requirements. It not only saves energy but also extends the pump’s lifespan by reducing wear and tear. They also help smooth out the flows through biological treatment processes, which in turn protects against pulsing or shock loading the sensitive bacteria within the process.

Flygt drainage pumps are a testament to engineering excellence in wastewater and dirty water management. By understanding their inner workings, we gain insight into the reliability, efficiency, and innovation behind these vital components of wastewater systems.

Next time you see a drainage pump at work, remember the impressive mechanics happening beneath the surface, thanks to companies like Flygt. Their commitment to cutting-edge technology ensures that wastewater is efficiently and effectively managed, protecting our environment and communities.
