Used Hydraulic Pumps

How Do Hydraulic Pumps Work?

Hydraulic pumps are the most critical and integral part of hydraulic machinery and equipment. They convert mechanical energy into hydraulic energy through the fluid movement, specifically oil, within the system. These pumps operate by creating a vacuum at its inlet. This forces fluid from the container into the inlet line and then to the pump. As the pumps mechanism rotates, it displaces this fluid, pushing it through the pumps outlet and into the hydraulic system under high pressure. Furthermore, this pressurized fluid travels to hydraulic cylinders and motors to perform various tasks, such as operating complex machinery or lifting heavy loads. The type of pump used varies based on the systems specific requirements, such as the fluid flow rate, the pressure required, and more.

Types of Hydraulic Pumps Offered by JM Industrial

• Gear Pumps:
• • External Gear Pumps: Comprise two intermeshed gears where fluid is drawn into the gears teeth and pushed around the casing. They are simple, reliable, and cost-effective.
  • Internal Gear Pumps: Feature one internal and one external gear with the fluid moving between them. They are quieter and more efficient than external gear pumps, often used for lower pressure applications.
• Vane Pumps: Use rotating vanes that move within a cam ring to create pressure. They are known for their smooth operation and are often used in applications requiring constant flow rates.
• Piston Pumps:
  • Axial Piston Pumps: Utilize multiple pistons arranged in a circular pattern around a central shaft. They are high-pressure pumps and often used in industrial applications.
  • Radial Piston Pumps: Have pistons arranged radially around a central crankshaft. They can handle high pressures and are typically used in heavy-duty applications.

Why Consider Used Hydraulic Pumps for Your Applications?

Used hydraulic pumps can be a practical choice for many reasons. Some of them are listed below.

• Availability:Sometimes, old hydraulic pumps or specific parts might become obsolete or their production may be stopped. Used hydraulic pumps can be easily available as replacements as new ones may take time. This way, you can minimize lead times and downtimes, thereby maintaining productivity. Used hydraulic pumps are ideal for projects with tight schedules or when a replacement is urgently needed due to equipment failure.
• Depreciation:New hydraulic pumps often experience a significant drop in value within a few years of their purchase. Opting for used hydraulic pumps can be a financially savvy decision, allowing buyers to avoid the initial depreciation. This approach saves money and offers better return on investment (ROI), making it an appealing option for those looking to maximize the efficiency of their existing system.
• Quality and Reliability:Most used hydraulic pumps have a track record of reliable performance if sourced from a reputed supplier. Many used pumps have been designed and maintained to withstand years of use and undergo lesser depreciation than new pumps. Also, its essential to check their maintenance logs and ensure proper inspection and testing have been conducted. 
• Eco Friendliness:Using hydraulic pumps can be an environmentally friendly choice as this reduces waste and demands manufacturing resources, energy consumption, and new resources. This immensely contributes to sustainability efforts. Used pumps extend the life cycle of the machinery and decrease the environmental impact associated with production and disposal. 
• Performance:Used pumps have undergone several cycles of testing and inspection. The initial manufacturing defects have likely been identified and corrected. Therefore, these pumps perform as expected, even during extreme conditions. Also, a good supplier would always ensure they are in good condition at the time of shipping.
• Cost Savings:Investing in used pumps is an excellent benefit as they are cost effective. Used hydraulic pumps come at a significantly lower price than new models. This is beneficial for businesses operating with tight budgets or looking to save on capital expenditures.

Factor Consideration When Choosing Hydraulic Pumps for Your Applications

You need to consider several factors when selecting hydraulic pumps for your applications. These factors help in ensuring optimal performance and reliability. Here are some important ones.

• The first important factor to consider is the type of hydraulic pump used. Today, different types of pumps serve different purposes. Gear pumps are suitable for high-speed, low-pressure applications, while vane pumps offer medium-pressure capabilities. The pump used must be compatible with the application. 
• Flow rate is critical to meet the system requirements as it determines how the hydraulic fluid can be moved through the system. This impacts the speed and efficiency of operations. The flow rate is measured in gallons per minute (GPM). 
• Next, the pump must handle the maximum operating pressure stated by the manufacturer. Overlooking this factor will result in pump failure and system downtime. Ensure the pumps rated pressure exceeds the systems maximum operating pressure.
• The fluid type and viscosity at operating temperatures should be compatible with the pump design. High-viscosity fluids require hydraulic pumps that can handle greater resistance, while low-viscosity fluids may need pumps with tighter tolerances to prevent leakage.
• Select high-efficiency pumps to reduce energy consumption and operating costs. This makes them more sustainable and cost effective over time.
• The pump should be compatible with other components of the hydraulic system, including valves, hoses, and reservoirs. Incompatibility will result in increased wear and tear or even system failure.
• It is important to consider the temperature ranges within which the pump will operate. Extreme temperatures can affect the pumps performance and the viscosity of the hydraulic fluid, resulting in inefficiencies or damage.
• Select the size and weight of the pump considering the support structure and space constraint. Oversized pumps can be difficult to install and maintain.
• Consider the ease of maintenance and availability of spare parts. Pumps that are easier to maintain and repair can reduce downtime and maintenance costs over the pumps lifespan.
• Last, the initial cost should be evaluated against the expected operational life and maintenance expenses. A low initial cost might lead to higher long-term expenses due to inefficiencies or frequent repairs.
