API OH3 Vertical Chemical Process Pumps

The TEFFIKO TGDP series of API OH3 cantilever vertical centrifugal pumps are suitable for transporting clean or slightly contaminated media. With a compact vertical layout, the motor is directly connected to the pump body, reducing the floor area by 60% compared to horizontal pumps.

● Impeller: It has a single - suction, radial, and closed - type structure, equipped with replaceable impeller wear rings and casing wear rings, which can save the cost of maintenance spare parts.

● Shaft Seal: Depending on different working conditions, packing seals can be flexibly selected.

● Pump Body: Radially split, sealed with a restricted gasket between the pump body and the pump cover. Pump bodies with a diameter of over 80 mm adopt a double - volute design.

● Pump Cover: A cooling chamber can be configured when necessary to cool the shaft seal chamber.

● Bearings: Lubricated with grease, there is a grease filling cup on the bearing cover, and the bearing bracket is normally designed without a cooling function.

Application Areas

1. Cryogenic Factories: Used to transport cryogenic media such as liquid ammonia and liquid nitrogen. The pump has excellent sealing performance and can adapt to low - temperature environments, ensuring the refrigeration system works properly, maintaining a low - temperature environment, and guaranteeing the freezing and storage quality of food.

2. Coal Mining Industry: Used to handle mine water containing impurities and corrosive substances. The pump is wear - resistant, corrosion - resistant, and has a large flow rate, ensuring coal mining safety. It is also used in coal washing to assist in efficient separation.

3. Power Plants: Used for boiler water make - up to meet the water demand; used in desulfurization and denitration systems to reduce harmful gas emissions. With stable performance, it ensures the continuous operation of power plants.

4. Marine Industry: The vertical centrifugal pump is resistant to seawater corrosion. It can transport various media on offshore platforms and is used to convey seawater and fresh water during seawater desalination.
