KP-35B Gear Pumps: Types and Components

The KP-35B gear pump is a widely used hydraulic component in industrial systems, designed to transfer fluid with consistent pressure and flow. Its reliable performance and simple design make it suitable for various machinery and hydraulic applications. 

Types of KP-35B Gear Pumps

KP-35B gear pumps can be categorized based on gear arrangement, drive method, and pressure handling capacity. Common types include:

External Gear Pumps

Utilize two external gears that rotate in opposite directions to transfer fluid. Simple and durable design suitable for general hydraulic systems.

Internal Gear Pumps

Feature an internal gear meshing with an external rotor. Offer smoother flow and can handle higher viscosities than external gear pumps.

Single-Stage Gear Pumps

Designed for applications with a single pressure stage. Suitable for moderate pressure and flow requirements.

Double-Stage Gear Pumps

Incorporate two pumping stages in series. Provide higher pressure or increased flow for industrial applications.

Direct Drive Gear Pumps

Driven directly by a motor or engine shaft. Common in machinery requiring compact and straightforward installation.

Belt or Coupling Driven Pumps

Use belts or couplings to connect to a driving motor. Allow flexible placement and speed adjustments.

These types allow operators to select pumps that meet system requirements for flow rate, pressure, and operational conditions.

Applications of the KP-35B Gear Pump

The KP-35B gear pump is versatile and can be applied in various industrial and mechanical systems. Common applications include:

Hydraulic Systems

Used to circulate hydraulic oil in presses, injection molding machines, and other industrial equipment. Provides consistent flow for smooth operation of cylinders and actuators.

Lubrication Systems

Supplies oil to engines, gearboxes, and machinery components. Maintains proper lubrication and reduces wear on mechanical parts.

Cooling Systems

Transfers coolant in industrial or mechanical systems. Helps maintain operating temperatures in hydraulic equipment and engines.

Fuel and Fluid Transfer

Used in fuel supply systems or chemical transfer applications. Capable of moving liquids with consistent pressure to prevent air pockets or irregular flow.

Agricultural and Construction Machinery

Provides hydraulic power for tractors, harvesters, and excavators. Supports operation of hydraulic motors and lifting mechanisms.

These applications demonstrate the adaptability and reliability of the KP-35B gear pump across multiple industries.

Components of a KP-35B Gear Pump

The KP-35B gear pump consists of several essential components, each contributing to its operational function.

Pump Housing

Encases internal components and provides structural stability.

Gears

Include driving and driven gears that transfer fluid through meshing rotation.

Shaft

Connects the driving gear to the motor or engine. Transfers rotational power.

Bearings

Support the shaft and reduce friction during rotation.

Seals

Prevent leakage of hydraulic or lubrication fluid. Maintain system pressure.

Inlet Port

Allows fluid to enter the pump. Positioned for smooth flow.

Outlet Port

Delivers pressurized fluid to the hydraulic system or application.

Cover Plate

Holds gears and internal components in place. Provides additional sealing.

Fasteners

Bolts and screws secure housing, cover plates, and components.

Each part of the KP-35B gear pump is critical for proper flow, pressure maintenance, and durability. Routine inspection and maintenance of these components ensure reliable operation and long-term performance.
