Hydraulic Pumps under 3.7kW are commonly used equipment in small and medium-scale hydraulic systems, responsible for generating and maintaining stable hydraulic oil pressure for the transmission process. The hydraulic pump lines (hydraulic pump motors) with a capacity of under 3.7kW well meet the demand for supplying appropriate oil flow, stable pressure, and flexible operation in various applications. With a structure

With a structure typically consisting of an electric motor, hydraulic pump head, drive shaft, coupling, oil seal, stator core, rotor, and bearings. These components are synchronously designed to create stable oil flow and pressure, helping the hydraulic system operate efficiently, durably, and well meet long-term working requirements.

Applications of Hydraulic Pumps under 3.7kW

• Mini hydraulic power packs:Hydraulic pumps are used to generate and maintain oil pressure for small-capacity hydraulic power packs in workshops and production lines.
• Independent hydraulic power stations: Suitable for systems requiring high-pressure oil supply to operate hydraulic cylinders or hydraulic motors during operation.
• Hydraulic lifting systems: Installed in power packs serving lifting tables, lifting platforms, or lifting mechanisms using hydraulic oil as the working medium.
• Small-capacity hydraulic pressing equipment: Provides stable oil flow and pressure for presses in the mechanical engineering, manufacturing, and material processing industries.
• Hydraulic cylinder control systems: The pump plays the role of generating hydraulic energy to help cylinders perform pushing, pulling, or lifting movements as required.

Advantages of Hydraulic Pumps under 3.7kW

• Sturdy design, easy installation: With a capacity of under 3.7kW, the pump has a relatively compact size, convenient for installation in hydraulic power packs with limited space.
• Stable oil pressure generation: The pump maintains regular oil flow and pressure, helping hydraulic mechanisms operate accurately and minimizing vibration during operation.
• Energy-saving: Moderate power helps reduce electricity consumption costs while still well meeting the usage needs of many small and medium-scale hydraulic systems.
• Durable operation: Internal components are designed to work continuously in a hydraulic oil environment, contributing to enhancing the service life and stability of the equipment.
• Ability to meet various pressure levels: The pump can be combined with valves and hydraulic power packs to serve various practical operating needs.
• High stability: The equipment is capable of maintaining stable performance for a long time, suitable for many industrial and mechanical applications.

Prices for Hydraulic Pumps under 3.7kW at Thanh Thai Motor

Notes when purchasing hydraulic pumps under 3.7kW

• Determine pressure: It is necessary to check the required pressure before selection to ensure the hydraulic pump meets operational needs and avoids overload conditions.
• Select appropriate oil flow: Pump flow directly affects the operating speed of the hydraulic cylinder or hydraulic motor. Choosing the wrong flow can make the system operate inefficiently.
• Check pump type used: Depending on practical needs, customers should choose gear pumps, vane pumps, or other pump lines to suit the working characteristics of the system.
• Pump driving motor power: The power must be compatible with the required pressure and flow to ensure the equipment operates stably and durably.
• Check installation dimensions and connection ends: Comparing flange dimensions, pump shafts, and oil ports will make installation or replacement smoother.
• Choose a reputable supplier: Priority should be given to products with clear origins, transparent technical specifications, and full warranty policies for peace of mind during use.

Frequently Asked Questions

Why does the hydraulic pump still reach sufficient pressure but the cylinder operates very slowly?

The cause is usually due to reduced pump flow because gear teeth or vanes are worn, the oil suction filter is clogged, or internal leakage occurs in valves and cylinders. At that time, pressure is still achieved, but the actual flow supplied to the actuator is insufficient.

Why does the pump shaft continue to leak oil even after replacing with the exact new seal?

Besides damaged seals, it is necessary to check shaft runout, bearing play, and journal wear. If the shaft is worn or eccentric, the seal lip cannot completely seal, leading to oil leakage again after a short operating period.

Why does the hydraulic pump make a loud noise after changing new oil?

This phenomenon is usually related to undischarged air in the oil, inappropriate oil viscosity, or air leakage in the suction line. If operated continuously for a long time, it can cause cavitation and damage internal parts of the pump.
