How to choose API 610 OH2, BB2, BB3 and BB5 pumps?

In oil refining, petrochemical, coal chemical and high temperature and high pressure equipment, purchasers often need to choose between API 610 OH2, BB2, BB3 and BB5 pumps. All four types of pumps can be used in critical processes, but there are significant differences in support methods, number of stages, casing construction, pressure capabilities and maintenance costs.

Working Principle of High Temperature Pump: High Temperature Medium Transport and Selection Guide

High-temperature pumps are mainly used to transport high-temperature thermal oil, hot water, molten salt, chemical liquids and other process media in chemical, petroleum, electric power, metallurgy and new energy devices. When purchasing a high-temperature pump, you should not only focus on the flow rate and head, but also comprehensively consider the medium temperature, vaporization pressure, corrosiveness, viscosity, sealing method and thermal expansion of the pump body. If the type is improperly selected, problems such as cavitation, leakage, bearing overheating, vibration or flow reduction may easily occur.

How to select an API 610 pump for refinery conditions? Selection Guide for Key Equipment in Refinery Units

Pumps in refineries operate in high-temperature, high-pressure, flammable, and corrosive media environments for a long time. They are important equipment to ensure the continuous operation of crude oil processing, hydrotreating, catalytic cracking, atmospheric and vacuum distillation and other units. The refining industry generally requires pumps with higher reliability, mechanical strength and long-term operation capabilities than ordinary industrial centrifugal pumps, so API 610 centrifugal pumps have become a common standard equipment in the petroleum, petrochemical and natural gas industries. API 610 sets out system requirements for pump design, materials, manufacturing, testing, and performance.

How to choose a slurry pump for mining and chemical applications?

Slurries in mines, tailings, hydrometallurgy and chemical production often contain solid particles and may have abrasive, corrosive, settling or crystallizing properties. Improper selection can easily cause impeller wear, insufficient flow, cavitation, clogging and seal leakage. When purchasing, you should not just compare the diameter and motor power, but should comprehensively analyze the medium parameters, system operating conditions, pump type, materials and shaft seal structure.

What causes pump vibration? Common causes and solutions

Engineers should make judgments based on vibration values, spectrum, flow, head, inlet pressure, current and temperature; buyers should provide complete working conditions during the inquiry stage to avoid long-term vibration caused by selection deviations.

Why does the centrifugal pump flow decrease?

Insufficient flow of centrifugal pumps in chemical, petroleum, electric power, metallurgy and industrial circulation systems does not necessarily mean that the pump itself is damaged. Changes in inlet conditions, increased pipeline resistance, impeller wear, insufficient rotation speed, or selection deviations may cause the actual flow rate to gradually decrease.

Vertical Submersible Pump Selection Guide

In sewage pools, chemical storage tanks, underground sump pits and process tanks, ordinary horizontal pumps often have difficulty operating stably due to insufficient suction conditions, volatile media or limited on-site space. Vertical submersible pumps place the pump body below the liquid surface and the motor and bearing system above the tank, which reduces the need for pump priming and reduces the risk of shaft seal leakage.

Magnetic drive pumps vs. mechanical seal pumps: which one is better for industrial applications?

When selecting pumps for chemical or industrial processes, magnetic drives and mechanical seals are two common options. The media hazards, solid particles, dry running risks, as well as flow, head, temperature, pressure and leakage requirements should be confirmed when purchasing. The two pumps control leaks completely differently.
