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.

In the selection and practical application of centrifugal pumps, household centrifugal pumps and chemical centrifugal pumps are often confused and arbitrarily replaced by users, triggering failures such as equipment damage, pipeline bursting and medium leakage. As a professional pump‑valve equipment brand TEFFIKO, we clarify that the two types of pumps have essential differences in material‑processing technology, sealing technology, structural design and working‑condition adaptability. Combining accurate parameters and practical working conditions, this paper elaborates on their differences to help users select models scientifically and avoid risks caused by mixed use.

Magnetic drive pumps feature seal‑free, zero‑leakage and high‑safety performance, and are widely used in chemical, pharmaceutical, environmental protection, petroleum and other industries for hazardous fluid transportation. Different from conventional centrifugal pumps, they adopt magnetic coupling transmission, equipped with high‑precision parts including ceramic shafts, graphite bearings, containment shells and impellers. Many rework faults, abnormal noise, medium leakage and rotor unbalance are not caused by natural aging, but by irregular disassembly, missing records and mis‑placement of components. Standard disassembly procedures, complete data recording and proper part protection are critical for magnetic drive pump maintenance.
