When customers choose the centrifugal pump products from China ATACH Industrial Pump Factory, they need to consider the NPSH(r) value for the pump usage.Otherwise, it is impossible to ensure that the pump can operate efficiently and safely. So, how significant is the impact of NPSH(r) on the pump's usage?NPSH(r), also known as the Required Net Positive Suction Head, is a key parameter for evaluating the anti-erosion performance of a pump. It has a direct impact on the stability and lifespan

For chemical media, ATACH industrial pumps usually recommend using alloy-silicon carbide sealing surfaces.In fact, for plain water, silicon carbide-graphite sealing surfaces are fully capable of performing the task.In the end face of mechanical seals, silicon carbide and alloys (typically referring to hard alloys such as tungsten carbide) are two core friction pair materials, which have significant differences in performance and are suitable for different working conditions.Main differences̶

Some of the regular customers who received pumps from ATACH Pump Company found that many of the stainless steel pumps had three holes on their impellers.So, what is the significance of these holes?Regarding the fact that the stainless steel impeller of the Chinese ATACH Industrial Water Pump Factory has three holes (usually three) on it is a common design.The main purpose is to balance the axial force and improve the self-priming performance.In multi-stage centrifugal pumps or certain single-sta

After the customer provides the required pump specifications, when Attek provides the pump quotation, they usually attach the performance curve chart of the pump to the quotation for the customer's reference. So, how should we interpret the data information on the performance curve chart?1. The performance curves of the water pump mainly include the flow-head curve (Q-H), the flow-power curve (Q-P), and the flow-efficiency curve (Q-η).2. First, check if the curve is smooth and if there are

The pumps of ATACH pump company are mainly divided into two categories: those made by casting and those made by stamping.The stamping centrifugal pumps and casting centrifugal pumps are two types of centrifugal pumps that adopt different manufacturing processes. They have significant differences in structure, performance, and application scenarios.• ;Stamping centrifugal pump;: Manufactured by stamping and welding process, it is formed through processes such as cutting, stampin

Regarding the statement made by China ATACH Industrial Water Pump Factory that three-phase water pumps must confirm the rotation direction before starting, according to the general technical principles and relevant materials in the water pump industry, it is crucial to confirm the rotation direction of three-phase water pumps before starting.The main reasons are as follows:• ;To ensure normal working performance;: For three-phase asynchronous motors-driven water pumps, the rota

For pumps used in environments with temperatures below 0℃, ATACH Pump Plant offers the following anti-freezing recommendations to prevent damage to the pump body due to the expansion of internal liquids when they freeze:Emptying the remaining water in the idle pump: For pumps that have been out of service for a long time, the residual liquid in the pump body and pipelines should be completely drained to prevent freezing at low temperatures, which could cause cracking of the pump body.Maintain c

Some customers in the centrifugal pump mechanical seal leakage, think that the leakage is large, do not replace, think that this is a small problem, in fact, should immediately replace the new mechanical seal, otherwise it will lead to more serious pump damage. The most direct and effective solution is to immediately stop the pump and replace the new shaft seal, while also checking the wear condition of the pump shaft.1. Identify the signs of damageThe most obvious sign of an axial seal failure

The ATACH pump has relatively few maintenance complaints in the global market, which is attributed to its systematic advantages in product design, quality control, after-sales service, and supply chain management.Product design and quality control are the foundation. The ATACH pump may adopt an optimized hydraulic model and durable materials (such as 304 stainless steel), and enhance reliability through precise casting processes, for example, similar brands have improved efficiency by 4.7% throu

The closely coupled centrifugal pump is usually called a direct-coupled centrifugal pump, while the centrifugal pump coupled through a coupling is usually referred to as a split-type centrifugal pump. (ATACH PUMP)Coupling centrifugal pumps and pumps with couplings are two common designs, and their advantages and disadvantages need to be evaluated based on specific application scenarios. The following is an objective comparison from key dimensions.;Structure and Installation:; The tig

Recently, a customer requested a centrifugal pump with a flow rate of 408 m³/h and a height of 15 m. They specified that the pump's inlet and outlet should be 200 mm x 150 mm. During our selection process, we found that when using a 200 mm x 150 mm pump, the pump's flow rate reached the maximum value at that point. We suggested to the customer that we change this parameter from 200 mm x 150 mm to 250 mm x 200 mm. Otherwise, we would not provide a quotation because even if we receive

When Attek's 50Hz centrifugal pump is used at 60Hz conditions, the motor power needs to be increased or the impeller diameter needs to be reduced. This is mainly due to the direct proportion relationship between the motor speed and frequency (n = 60f/p, where f is the frequency and p is the pole pairs). When the frequency rises from 50Hz to 60Hz, the speed increases by 20%.1 This will cause significant changes in the pump's flow rate, head, and shaft power, which may exceed the original

Some customers have limited space conditions. When installing the coupling for the pump products manufactured by ATACH Industrial Pump Factory, sometimes they use a hammer to strike forcefully at the motor shaft end or the pump shaft end. This method is not advisable. So, how should the coupling be installed at the motor shaft end and the pump shaft end?The installation of the coupling for a centrifugal pump is a crucial step to ensure a reliable connection between the pump and the motor. It mus

The motors used in the centrifugal pumps of ATACH Industrial Pump Factory are generally YE2/YE3.If required by the customer, YE4/YE5 energy-saving motors can also be installed.So, what are the impacts of using pumps with different energy efficiencies?The energy efficiency of the motor has significant impacts on the use of centrifugal pumps, mainly manifested in aspects such as energy consumption, operating costs, system performance, and environmental benefits.;Energy consumption and operat

The static rings of the mechanical seals of chemical centrifugal pumps are sometimes equipped with O-rings and sometimes not. What are the advantages of having O-rings? Attek Pump Factory analyzes as follows:The O-ring configuration of the static ring in the centrifugal pump mechanical seal is mainly to establish a reliable static seal between the static ring and the gland, in order to prevent the medium from leaking at this connection point.The O-ring deforms under pre-compression to fill the s

Customers who have cooperated with Attek Pump Factory (Dongguan Industrial Pump Factory) are aware that Attek's salespeople always ask about the specific gravity of the medium before making a quotation. So, is the specific gravity of the medium really important? What aspect of the pump does it mainly affect? The analysis is as follows:When selecting the model, the Chinese Aitek Pump Factory inquired about the density of the medium from the customer, mainly to ensure that the selected pump ca

When transporting oil-based media such as diesel and gasoline, Attek Pumping Industry usually recommends using chemical pumps made of copper for customers. Why can cast steel, stainless steel, and other materials also be used for transporting oil? Why aren't they preferred instead?When transporting oil-based media in chemical pumps, copper impellers (such as bronze impellers) are often the preferred choice, mainly due to their material properties and safety requirements. The following provid
