PUMPS CUC8-30B 50HZ
Our water pump is constructed with a heavy-duty stainless steel pump head, aluminum pump housing, and PES impeller, rust-proof, and waterproof. Brass fittings and a water stop will come with the pump for corrosion-proof and leakage-proof. The powerful water pump has max. 40 L/min water flow, max. 10 bar pressure and max. 20 ft head lift. In addition, the super silent running property(about 25dB) can provide you with a quiet pump: high performance but low noise.
The powerful water circulator pump has four power control switches in 46/67/93W. In addition, the super silent running property(about 25dB) can provide you with a quiet pump: high performance but low noise.

About this item
Stainless Steel Material
Our water pump is constructed with a heavy-duty stainless steel pump head, aluminum pump housing, and PES impeller, rust-proof, and waterproof. Brass fittings and a water stop will come with the pump for corrosion-proof and leakage-proof.
Large Flow & Quiet Running
The powerful water pump has max. 40 L/min water flow, max. 10 bar pressure and max. 20 ft head lift. In addition, the super silent running property(about 25dB) can provide you with a quiet pump: high performance but low noise.
Adjustable Speed Switch
This water circulator pump features a three-power control switch in 46/67/93W. It is convenient for you to adjust the flow rate to your different requirements. Meanwhile, the built-in electrical sensor automatically enables the pump to start up or shut off according to the water flow.
Easy Installation
Our water pump can be used directly to drinking water pipelines with a wrench, fitting with an NPT 3/4" inlet/outlet hose. The water taste of lubricating oil will disappear after 3 to 5 times of use. The shaft of the pump should be kept horizontal after installation.
Wide Application
The water pump is suitable for many applications, such as city buildings, suburban villas, houses, water and pressurized with industrial equipment, air conditioning, boilers, solar circulating system, water heater system, and so on.
This water pump is made of a premium stainless steel pump head and aluminum pump housing and features high power efficiency, low energy consumption, ample water flow, low noise running, and easy installation. Convenient for daily use, perfect for family water heating systems, such as remote villas, cabins, etc.
Note: Never let the water outlet face downward, or the valve will be plugged up.

Pumps are widely used in oil and gas, petrochemical, chemical, steel, electric power, food and beverage, pharmaceutical, and water treatment industries.
How to control the output flow of the pump economically and effectively has caused great discussion. It was once popular to use frequency conversion speed regulation to control the output flow and cancel all types of control valves to control the flow. At present, there are four widely used methods in the market: outlet valve opening adjustment, bypass valve adjustment, impeller diameter adjustment, and speed regulation control. Now let's analyze and discuss the characteristics of various methods one by one.
Four methods of pump flow control
Outlet valve opening adjustment
In this method, the pump is connected in series with the regulating valve of the outlet pipeline, and its actual effect is like using a new pump system. The maximum output head of the pump does not change, but the flow curve is attenuated.
Bypass valve regulation
In this method, the valve is connected in parallel with the pump, and its actual effect is like using a new pump system. The maximum output head of the pump changes and the characteristics of the flow curve also changes, and the flow curve is closer to the linear.
Adjust impeller diameter
This method does not use any external components and the flow characteristic curve changes with the diameter.
Speed control
The change of impeller speed directly changes the flow curve of the pump, and the characteristics of the curve do not change. When the speed decreases, the curve becomes flat, and the head and maximum flow decrease.
The overall efficiency of the pump system, the outlet valve regulation, and bypass regulation methods both increase the pipeline pressure loss, and the pump system efficiency is greatly reduced. The impeller diameter adjustment has little effect on the efficiency of the whole pump system, and the speed control method does not affect the system efficiency, as long as the speed is not less than 50% of the normal speed.
The energy consumption level of the water pump
Assuming that the output flow of the pump is adjusted from 60m3/h to 50m3/h through the above four methods, and the power consumption when the output is 60m3/h is 100% (at this time, the pressure head is 70m), how do several flow control methods affect the power consumed by the pump?
1)The opening of the outlet valve is adjusted, and the energy consumption is 94%. When the flow is low, the power consumption is large.
2)Bypass regulation, the by-pass valve reduces the pump head to 55m, which can only be achieved by increasing the pump flow. As a result, energy consumption increases by 10%.
3)After adjusting the impeller diameter and reducing the impeller diameter, the output flow and pressure of the pump are reduced, and the energy consumption is reduced to 67%.
4)Speed regulation control, speed reduction, pump flow and head reduction, energy consumption reduced to 65%.
Application field
① In the production of chemical and petroleum sectors, most of the raw materials, semi-finished products, and finished products are liquids, and the production of semi-finished and finished raw materials into semi-finished products and finished products needs to go through complex technological processes. During these processes, pumps play a role in transporting liquids and providing pressure flow for chemical reactions. In addition, in many installations, pumps are used to adjust the temperature.
② In agricultural production, pumps are the main irrigation and drainage machinery. my country's rural areas are vast, and a large number of pumps are needed in rural areas every year. Generally speaking, agricultural pumps account for more than half of the total output of pumps. Pumps are also the most used equipment in the mining and metallurgical industries. The mine needs to be drained by pumps, and in the process of beneficiation, smelting, and rolling, pumps are needed to supply water.
③ In the power sector, nuclear power plants need nuclear main pumps, secondary pumps, and tertiary pumps, and thermal power plants need a large number of boiler feed pumps, condensate pumps, oil and gas mixing pumps, circulating pumps, and ash pumps.
④ In national defense construction, the adjustment of aircraft flaps, tail rudders, and landing gear, the rotation of warships and tank turrets, and the ups and downs of submarines all require pumps. High pressure and radioactive liquid, and some also require the pump without any leakage.
⑤ In short, whether it is aircraft, rockets, tanks, submarines, drilling, mining, trains, ships, or everyday life, pumps are needed everywhere, and pumps are running everywhere. That's why the pump is listed as a general-purpose machine, which is a major product in the machinery industry.
⑥ Electric pumps i.e. pump driven by electricity. The electric pump is composed of a pump body, a water lift pipe, a pump base, a submersible motor (including cables), and a starting protection de
