Dry running (dry operation/idling) of a centrifugal pump refers to an abnormal operating condition where the pump cavity lacks liquid, has insufficient liquid volume or loses suction fluid while the pump keeps running. It is a highly destructive fault that frequently occurs in industrial centrifugal pumps. Centrifugal pumps rely on conveyed liquid for lubrication, cooling and hydraulic pressure stabilization. Once deprived of medium protection, internal components will rub directly against each other and accumulate heat rapidly. Even a short period of idling can cause irreversible damage and even complete pump failure leading to shutdown.

Chemical process pumps are core fluid transportation equipment in industries such as chemical engineering, petroleum, and pharmaceuticals. As special types of centrifugal pumps, they convert mechanical energy into fluid kinetic energy and pressure energy by centrifugal force, and are engineered for harsh operating conditions involving high temperature, high pressure, corrosion resistance and continuous operation.

Centrifugal pumps are core equipment used in industrial and municipal fields and generate severe vibration during operation. The equipment foundation, preformed anchor holes and anchor bolts constitute key concealed works that guarantee unit stability. Many on-site faults such as pump body deviation, resonance, bearing overheating and bolt fracture are usually caused by non-standard construction of preformed holes or substandard bolt installation. This document elaborates on the key guidelines for construction of preformed anchor holes and installation of anchor bolts for centrifugal pumps.

Pumps are core equipment for fluid transportation. Most pump failures stem from improper operation, installation, model selection and maintenance, rather than product quality issues. Such issues may lead to air binding, cavitation, leakage, insufficient flow rate and increased power consumption. In severe cases, they can result in equipment damage and production shutdowns. Omron Tech Pumps has long been dedicated to the field of fluid transportation equipment.

API PLAN 53B flush plan is a mainstream barrier fluid circulation and pressurization system for zero-leakage seals under working conditions with high-pressure, toxic and flammable media, which strictly complies with the API 682 industry standard. Many pump manufacturers and operation & maintenance engineers fail to distinguish the pressurization logic of Plan 53A, 53B and 53C. This document fully explains the working principle of API PLAN 53B flush plan.

Centrifugal pumps are core equipment for fluid transportation and widely used in civil and industrial fields. Though they share the same working principle, domestic centrifugal pumps and chemical centrifugal pumps differ fundamentally in design positioning. The former is designed for lightweight and cost-effective clean water delivery, while the latter is built to withstand harsh working conditions featuring strong corrosion and heavy loads. The two types must never be used interchangeably. Below is a concise overview of their core differences and key selection tips from five perspectives.

Fluid transportation in chemical production relies heavily on industrial pumps. Under harsh working conditions involving strong corrosion, high viscosity, highly toxic and hazardous media, accurate pump selection is the key to ensuring safe and stable production lines and reducing operation and maintenance costs. Below is a detailed overview of core pump types and selection strategies for the chemical industry.

This article summarizes the core differences between the two types of pumps in an all-round manner. The content is presented in an easy-to-understand way to accurately meet various industrial production needs and help you quickly solve pump selection problems.

As a centrifugal pump researcher, this article sorts out five core specifications for the daily use of high-temperature oil pumps to help users effectively extend equipment service life and cut downtime maintenance costs.

Benzene-containing wastewater is highly toxic, volatile, flammable, explosive and corrosive to organic solvents. Pump selection must comply with three mandatory standards:
