The split case centrifugal pump is a cornerstone of many industrial and municipal fluid handling systems, prized for its high capacity, efficiency, and durability. However, to fully realize its performance and service life, a proactive and standardized approach to operation and…
During operation, split case centrifugal pumps may sometimes consume excessive power, which not only increases operating costs but also potentially reduces equipment lifespan. This article analyzes the potential reasons for excessive power consumption in split case centrifugal pumps and proposes…
Split case pumps are widely used in water supply, HVAC, power plants, and industrial systems. One of their most reliable and cost-effective sealing solutions is the packing gland (stuffing box). Unlike mechanical seals, packing glands rely on controlled leakage to…
Cavitation is one of the most common and destructive hydraulic problems affecting split case pumps. It occurs when local pressure in the fluid drops below its vapor pressure, causing vapor bubbles to form and collapse violently near the impeller or…
Split case pumps are widely used in water supply, HVAC, and industrial applications due to their high efficiency and reliability. However, during continuous operation, the overcurrent components—especially the pump casing—are subject to wear and erosion caused by impeller friction, cavitation,…
1. Understanding the “Pump Curve” vs. the “Impeller Segment Curve” Manufacturer-provided performance curves for submersible vertical turbine pumps are usually obtained under ideal laboratory conditions: precise installation, clean water, ambient temperature, and standard atmospheric pressure. These curves are commonly referred…
A vertical turbine pump (VTP) is a widely used pumping solution for industrial water supply and drainage, agricultural irrigation, mine dewatering, power plants, and fire protection systems. Its compact structure, ability to operate in deep wells or sumps, and capacity…
Vertical turbine pumps are essential in industries such as oil & gas, petrochemicals, and power generation. To ensure safety, reliability, and performance, two of the most influential international standards that govern their design and manufacturing are API 610 (American Petroleum…
1. Introduction The operating temperature of motor bearings in a split casing pump is critical for reliable performance and long service life. Bearings are the most vulnerable components of the pump motor, and excessive temperatures can lead to premature wear,…
Split case double suction pumps (horizontal split-case centrifugal pumps) are widely used in high-flow scenarios such as municipal water supply and power plant circulation systems due to their symmetrical structure and ease of maintenance. However, the impellers are prone to…
