Mechanical seals are core sealing components for fluid‑handling equipment such as centrifugal pumps, reaction synthesis kettles, turbo‑compressors and submersible motors, ensuring leak‑free and stable equipment operation. Nevertheless, their performance and service life depend not only on the product itself but also heavily on selection matching, installation precision and operation‑maintenance practices. Industry statistics show that over 80 % of seal leakage, premature failure and frequent replacement issues stem from improper selection, non‑standard installation or operational errors. Combining industry standards with field practical experience, Teffiko addresses precise type‑selection and installation‑precision control to achieve more reliable and efficient equipment operation.

The Teffiko progressive cavity pump is a positive‑displacement conveying equipment. It consists of an eccentric helical rotor mated with a double‑helical surface bushing (stator) to form closed cavities for medium displacement. It features stable pulsation‑free flow, low shear force, strong self‑priming capacity and broad medium compatibility. It is especially suitable for conveying high‑viscosity media, media containing hard particles, fibrous materials and shear‑sensitive substances prone to tearing.

Crude oil transfer pumps are critical equipment in oilfield production, refineries, storage depots, and oil-gas transportation. Due to crude oil's unique properties — wide viscosity range, impurities, flammability, explosiveness, and large temperature fluctuations — ordinary water pumps cannot meet the demands. So how do you select the right pump for different working conditions?

API 610 serves as the core general standard for horizontal centrifugal pumps in petrochemical, oil‑gas and chemical industries. This standard classifies industrial centrifugal pumps into three core configurations: OH overhung pumps, BB between‑bearings pumps, and VS vertical suspended pumps. With years of in‑depth R&D and manufacturing expertise in API 610‑compliant pumps, Teffiko delivers highly reliable fluid‑transport solutions for diverse industries through standardized structural design and rich experience in adapting to demanding operating conditions.

Many industrial users ask about the practical uses of liquid ring vacuum pumps during equipment selection. As reliable industrial vacuum equipment, Teffiko liquid ring vacuum pumps adopt a unique structure suitable for humid, dusty and corrosive working conditions, outperforming traditional screw and rotary vane pumps. Designed for rough vacuum applications, they provide stable oil-free negative pressure and basic gas compression for chemical, pharmaceutical, food, power and light industry processes. This article by Teffiko systematically introduces their working principles, core advantages, system types, industrial applications and maintenance tips.

As a mainstream industrial positive‑displacement conveying equipment, Teffiko screw pumps feature stable operation, pulse‑free delivery and strong medium adaptability. They are widely used in sewage treatment, chemical industry, food processing, petroleum, building materials and many other industries. Screw pumps rely on precise coordination of components to form closed chambers for medium delivery. Under long‑term operation, components suffer wear and failure due to friction, corrosion, dry‑running and pressure shock. To effectively reduce equipment failures, avoid downtime losses and cut operation‑and‑maintenance costs, it is critical to master the list of wearing parts, their wear characteristics and standardized maintenance practices.
