Construction companies utilize various types of heavy lifting equipment to carry out activities such as lifting and lowering of formwork structures, heavy machinery, as well as erecting buildings. With technological advancements in the construction industry, several kinds of lifting equipment are now available on the market. Having designed the most comprehensive systems in the business, we have found that the hydraulic pumps, climbers and jacks in our heavy lifting systems work well. They are used for placement, removal or shifting of heavy loads that require a high degree of accuracy, precision and safety. 

We supply hydraulic devices for slipforming, heavy lifting and transportation, and steel tank construction. This equipment comes with hydraulic pumps and motors to conduct efficient and effective operations.

How Does a Hydraulic Pump Work?

We develop, manufacture and test hydraulic pump systems that can withstand harsh working environments around the globe. Such high-pressure hydraulic pumps are designed to operate 24 hours a day from high temperatures in the equatorial region to freezing temperatures in the Nordic region. So how do hydraulic pumps work?

Let’s start with the basics. Hydraulic slipform construction methods and heavy lifting equipment require hydraulic pumps and accessories. In the simplest terms, a hydraulic pump is a mechanical device that converts mechanical power into hydraulic energy. Here is a closer look at the mechanism used in a hydraulic pump. It generates flow with power that is sufficient to overcome any pressure induced by the load. The operation of a hydraulic pump comprises two fundamental functions: firstly, the mechanical action creates a vacuum at the pump inlet. This, in turn, allows atmospheric pressure to force liquid into the pump’s inlet line. Secondly, the mechanical action delivers this liquid to the pump outlet and then forces it into the hydraulic system.

Hydraulic Pumps and Motors: Components

Due to their various uses and mechanisms, there are several classifications of hydraulic pumps: clutch, gear, piston, rotary, fixed and variable displacement pumps, etc. We supply hydraulic power packs that are high-pressure hydraulic pumps with various capacities with hydraulic lines. The pump units range from different capacities to motor size and working pressure.

Listed below are the main components of our hydraulic pumps:

• Hydraulic system
• Electric motor
• Oil pump
• Oil reservoir
• Operating valve
• Ball valve
• Filter cartridge
• Pressure gauge
• Pressure guided return valve
• Return line oil filter

Now that we have a fair idea about the working and components of hydraulic pumps, let’s understand what goes into their maintenance, upkeep and repair.

Hydraulic Pump Maintenance

The lack of maintenance of hydraulic systems is the leading cause of system and component failure. Hence, it is important to understand the proper maintenance techniques of a hydraulic pump system. This includes preventative maintenance as well as corrective maintenance. 

Listed below are some basic maintenance procedures and protocols to be followed:

• Identify the hydraulic system’s operating conditions (24/7, hot/cold environment or maximum flow and pressure)
• Understand the requirements and operating parameters for preventive maintenance and hydraulic fluid
• Check the level of hydraulic fluid inside the pump
• Check the hydraulic system for leaks
• Change the hydraulic filters and filter the hydraulic fluid
• Clean the inside and outside of the hydraulic reservoir
• Check and record the hydraulic pressure and pump flow

Regular maintenance of hydraulic pumps and motors will ensure maximum output and greater longevity. For electric hydraulic pumps and accessories, it is essential to opt for a company that is well-stocked with products and has a credible reputation for after-sales maintenance of spare parts. At Bygging Uddemann, we have designed and manufactured hydraulic controlled heavy lifting equipment like hydraulic pumps, climbers and jacks for over fifty years and our equipment is still in use around the world.
