The SH1 internal gear pump operates on the principle of positive displacement.
It consists of two gears – an external rotor and an internal rotor – which mesh together. The fluid is trapped between the teeth of the gears and is transported from the inlet to the outlet of the pump in a continuous and uniform flow. This design ensures a constant and pulsation-free flow.
Materials and Construction:
SH1 internal gear pumps are typically constructed from robust materials like cast iron, stainless steel, or bronze, which makes them suitable for a wide range of fluids, including corrosive and abrasive substances. The careful selection of materials allows the pump to withstand challenging operating conditions and ensures its longevity.
One of the standout features of the SH1 internal gear pump is its ability to handle a broad viscosity range. These pumps are capable of handling both low and high viscosity fluids, making them versatile for various applications, including transferring oils, fuels, chemicals, and even thicker substances like molasses or adhesives.
Flow Rate and Pressure:
The SH1 internal gear pump can deliver a wide range of flow rates and pressures. Flow rates typically range from a few liters per minute to several hundred liters per minute, depending on the pump's size and design. It can generate pressures of up to several hundred PSI, making it suitable for both low and high-pressure applications.
These pumps are designed to operate within a broad temperature range.
Depending on the materials of construction and the specific application, the SH1 internal gear pump can handle temperatures from -40°C to well above 200°C, making it adaptable to extreme temperature environments.
The SH1 internal gear pump is renowned for its high efficiency. Its positive displacement design ensures that every revolution of the gears delivers a consistent volume of fluid. This efficiency makes it an excellent choice for applications where precise and accurate flow control is crucial.
To accommodate different applications and fluid properties, SH1 internal gear pumps offer various seal options, including mechanical seals, lip seals, and packing glands. This versatility allows users to select the most appropriate sealing method for their specific needs, whether for sealing aggressive chemicals or sanitary applications.
SH1 internal gear pumps are available in different mounting configurations, including base-mounted, close-coupled, and flange-mounted options. This versatility simplifies installation and integration into existing systems.
Maintenance for SH1 internal gear pumps is relatively straightforward. Routine checks and maintenance include inspecting seals, lubrication, and ensuring proper alignment. The pump's simple design and durable materials contribute to its long service life.
