Vertical Chemical Pump

The shaft of Teffiko magnetic pump is manufactured from high-carbon chromium bearing steel. After heat treatment, its hardness reaches 58-62 HRC, delivering outstanding wear resistance and deformation resistance. However, during long-term operation, erosion by impurities, lubrication failure, dry running and overload may lead to shaft wear, bending, thread damage and keyway failure, which further cause vibration, abnormal noise and reduced flow rate. To avoid the high cost of replacing a brand-new shaft, this paper systematically sorts out the damage judgment criteria, complete repair procedures, maintenance precautions and assembly & commissioning key points for Teffiko magnetic pump shafts in accordance with industrial standards.

Sewage pumps are vital in wastewater management, adapting to diverse scenarios with specialized designs. Their robust structure handles impurities via widened flow passages and cutting devices, while varied types like submersible and centrifugal models cater to different installation and sewage conditions. Efficient selection based on factors like solid content and head ensures seamless operation across municipal, industrial, and construction sectors, underpinning effective sewage conveyance and treatment.

As a professional centrifugal‑pump brand and original manufacturer, Teffiko has years of in‑depth experience in R&D, production and on‑site operation & maintenance of industrial pumps. We have found that centrifugal pumps in chemical, water treatment and industrial circulating water‑supply systems frequently suffer sudden drop in pump head, insufficient discharge pressure and sharp flow reduction. In many cases, such unalerted malfunctions do not stem from pump damage, but from abnormalities in pipelines, motors, operating conditions or internal components. This article summarizes common causes and corresponding solutions concisely by Teffiko centrifugal‑pump manufacturer, helping users conduct rapid troubleshooting and restore normal equipment operation.

Teffiko provides professional support for cast iron pump selection. In the petrochemical production system, as the most widely used and cost-effective basic conveying equipment, cast iron pumps are indispensable "conveying experts" in industrial plants, responsible for conveying crude oil, clean water, light oil and other materials under neutral medium and conventional working conditions. According to statistics, cast iron pumps account for more than 40% of pumps used in petrochemical industry. With the advantages of low material cost, simple structure and convenient maintenance, they are the first choice for small and medium-sized petrochemical enterprises and conventional conveying scenarios.

"Our pump burned out the motor again!" "Electricity bills for water pumps are ridiculously high this month. Did we choose the wrong pump?"
