Generally speaking, it is not necessary to install a bottom valve because corrosion-resistant pumps usually have their own check valves at the inlet. After the corrosion-resistant self-priming pump is shut down, the liquid in the pump chamber cannot flow back to the original pool and is stored in the pump chamber. Therefore, there is no need to add liquid during the second use. However, it does not mean that the corrosion-resistant self-priming pump cannot be equipped with a bottom valve. Installing a bottom valve will improve the effect, because if the one-way valve is sometimes damaged, the bottom valve will serve as a guarantee and will not idle after installation. If a bottom valve is installed, the effect will be better, because if the one-way valve is sometimes damaged, the bottom valve serves as a guarantee and will not idle. After installing the bottom valve, it will also effectively ensure the effective suction range of the pump. Another special case, but if the difference in suction height is too large, or the diameter of the suction pipe is too large, and the volume exceeds the storage capacity of the corrosion-resistant self-priming pump chamber, it cannot work normally. At this point, a bottom valve must be installed to ensure safe and fast self- priming. Therefore, the self-priming pump does not require the installation of a bottom valve, but it does not mean that the bottom valve cannot be installed. After the installation of the bottom valve, the suction range of the pump will be more guaranteed, especially for some small corrosion-resistant self-priming pumps. Due to the fact that small corrosion-resistant self-priming pumps generally do not have one-way valves and achieve self-priming effect through the vacuum generated by the instantaneous pump body, the suction effect of the pump will be better after the bottom valve is installed.

Naphtha transfer pump Twin screw pump is a rotary upright pump, with gears and bearings located externally and not in contact with the conveyed liquid. The pressure, flow rate, temperature, and viscosity of the conveyed liquid have a wide range, such as gasoline, hydrocarbons, seawater, high viscosity liquids such as asphalt, tar, adhesives, molasses, and corrosive media such as acids and alkalis. Medium viscosity: 1-1500mm2/s Pump pressure range: 4.0MPa Flow range: 1-2000m3/h Temperature range: -15 to 280 degrees Celsius Pumps can transport media such as lubricating oil, hydraulic oil, cutting oil, cooling oil, wax, tar, light oil, liquefied petroleum gas, crude oil, heavy oil, and asphalt. Oil and gas Twin screw pumps are ideal pumps for transporting crude oil, natural gas, water, and solid mixtures. They can be used on land and at sea. The pump can operate dry and transport media containing gas. Its compact design and special thread profile ensure long-distance pipeline transportation. Application of multiphase crude oil transportation, thermal power plants, and crude oil storage. ocean Twin screw pumps can be used on oil tankers for loading and transportation, lubricating the main engine, and transporting tar, asphalt, light and heavy fuel oils, crude oil, and chemicals. Petrochemical industry, refinery This pump can transport low viscosity liquids, including media with neutral, alkaline, acidic, or gaseous or abrasive materials Applied to heavy oil, asphalt, tar, heavy fuels, naphtha, and chemical products chemical industry Whether low viscosity or high viscosity, it can transport various liquids with corrosiveness and solid particles, Pumps are used for transporting polymers, coatings, slurries, liquid sulfur, or chemicals. 1、 Fluid characteristics of mixed naphtha Blended naphtha refers to a mixture of naphtha and a certain proportion of light hydrocarbons. Due to the addition of light hydrocarbons, the fluid characteristics of mixed naphtha are more complex than those of pure naphtha. Specifically, blended naphtha has the characteristics of high viscosity and high specific gravity, and the viscosity decreases with increasing temperature, which poses certain difficulties in pump selection. 2、 Characteristics of screw pumps and centrifugal pumps 1. Screw pump Screw pump, also known as rotary thruster, works by pushing liquid into the pipeline through the rotation of the screw. The main characteristics of screw pumps are strong adsorption capacity and pressure stability, and the ability to transport high viscosity liquids. 2. Centrifugal pump A centrifugal pump refers to a type of pump that uses centrifugal force to push liquid into a centrifugal casing, and then discharges it through an outlet pipe. The main characteristics of centrifugal pumps are high flow rate and stable pressure, but they are prone to blockage when transporting high viscosity liquids. 3、 Choose the appropriate pump Due to the fluid characteristics of blended naphtha itself, when selecting a pump, it is necessary to consider both flow rate and pressure stability, as well as adaptability to high viscosity liquids. In this case, screw pumps are more suitable for transporting mixed naphtha. The adsorption capacity and pressure stability of screw pumps can effectively solve the problem of transporting high viscosity liquids. In addition, the repair and maintenance costs of screw pumps are relatively low, and their reliability is high. Although centrifugal pumps have advantages in terms of flow rate, they are prone to blockage and overload when transporting high viscosity mixed naphtha, which can cause unnecessary problems during operation

3GC Self priming triple screw pump for fuel oil transfer The three spindle screw pumps consist of general design type 3G, marine usage pump 3GC and three screw pumps of special design. The three-spindle screw pump is a positive displacement rotary pump. Inside the pump casing, as the flanks of teeth of drive screw and idler screws are engaged and the screws are also matched with the three inset holes, several sealed moving chambers are thereby formed in between the pump inlet and outlet end. The closed chambers will take the medium inside to move from the inlet end axially and let flow pressurized progressively, to have a continuous, constant, axial flow pressured liquid. Triple screw pumps are suitable for pumping various kinds of non-corrosive oil without contents of solid grains and liquids similar to lubricating oils. The viscosity could also be pumped after heating up (lowering down the viscosity) The flow range : 0.2 to 590m3/h, Max. working pressure:100bar, the highest temperature of pumped liquids: 150 degree Celsius. 1. Simple in construction: The pump has quite a few construction forms. General for small flow range (0.2 to 6.5m3/h), pump casing and insert is made in one part. Mechanical seal is used as the pump shaft seal. For marine application pumps, installation forms could be horizontal or vertical, with marine AC or DC drivers. 2. Long life time: As the drive screw is driven by motor and there is no mechanical contact between the drive screw and the idler screws, the idler screws are hydraulically driven by the pressured liquid, between the drive screw and idler screw, screws set and insert, an oil film is formed, so the mechanical frication is minimized and a longer life is ensured. 3. The medium to be pumped is in a manner of constant axial flow movement, so the pressure pulsation is almost eliminated, meanwhile the noise is lowered, and as the moving parts have a little inertia, the starting torque and vibration is very little. 4. Pump have a very high suction capability. 5. In order to ensure the safe working of pump, motor, piping system, pumps for a capacity higher than middle flow range are all equipped with safety valves. Pressured oil will circulate back to suction chamber.
