Let's talk about the differences between OH3 and OH4 centrifugal pumps. Both are horizontal centrifugal pumps, but they have different design focuses and are used in different applications.
First, let's look at the structure. The OH3 has an independent bearing housing, and the pump shaft and motor shaft are separate, connected by a coupling. Its impeller is supported on both sides, so the force is stable, resulting in low vibration during operation, making it suitable for long-term high-intensity work.
The OH4, on the other hand, features a "overhung" design, with the bearing housing integrated with the pump casing, making the structure more compact. However, with this design, the impeller is somewhat like a cantilever, and the force is borne entirely by the bearing at one end, so it is not suitable for ultra-high pressure and large flow tasks.
The OH3 centrifugal pump, with its stable structure and strong bearing capacity, is not only suitable for high-pressure and large-flow scenarios such as high-pressure transportation in the chemical industry and large-scale circulation systems, but also more reliable when transporting high-temperature or moderately viscous media like hot oil and syrup. This is because its stable structure is not easily affected by the properties of the medium, which could otherwise interfere with operation.
The OH4 centrifugal pump has the advantages of a simple structure, small size, space-saving installation, convenient maintenance, and high cost performance. It is not only suitable for small and medium-sized transportation scenarios such as ordinary water supply and low-pressure industrial circulation, but also ideal for occasions like agricultural irrigation pumping stations and reflux pumps in small sewage treatment plants, where the requirements for equipment are not extreme, and more emphasis is placed on cost performance and easy installation.
In general, the OH3 is sturdy and durable, suitable for high-pressure and heavy-load conditions; the OH4 is compact and flexible, suitable for light-load conditions. When choosing, just consider the specific pressure, flow requirements, and installation conditions.
