Serving liquids in technological tanks at production facilities, workshops and service points is a non-standard task that special equipment provides. Its features include resistance to chemically strong, corrosive and high-temperature environments. These qualities are possessed by an electric barrel pump designed for pumping both neutral and aggressive liquids.
Pump design
Despite the complexity and responsibility of the operations performed, such devices have a fairly simple device. The basis is formed by three functional parts:
- Flexible hose. Performs the function of draining from the target tank. As a rule, it is made of synthetic materials, resistant to damage, with polymer alloys like polyvinyl chloride.
- Holder for refueling. The upper part of the device, which is connected to the refueling gun, hose and suction pipe. In modern design, barrel electric water pumps in this part can have an additional purification filter and an electronic control unit with an LCD display to control fluid parameters. In the same area, a motor with an electrical strapping or a battery pack can be placed.
- Suction pipe. Coming from the holder down vertically. At the lower end has a main filtration device. Also made from chemically and physically resistant materials.
Depending on the configuration, the basic set of the pump may include sensors, rings and seals, fittings, adapters, various nozzles, etc.
Varieties of pump
To begin with, it is worth separating the process and watering barrel pumps. They are united by the fact that they are immersed in a tank or tank, and in the process of work, in addition to the main task of pumping, they can perform preliminary cleaning. At the same time, barrel electric watering pumps are additionally provided with a float mechanism for controlling water in the tank, which protects the system from idle dry running. In pumps for process fluids, this problem is solved by special devices and electronics. Since the work process most often occurs in an industrial environment, higher demands are placed on the control.
Further directly technological pumps can be divided according to the principle of energy supply. They can work both from a 220 V network, and from batteries with the aforementioned batteries. So, an electric barrel pump for pumping oil with its own batteries can also be used in the remote in the field. For example, if you need to fill the car with technical fluid at a distance from the service station.
Device specifications
From the point of view of productivity, the volume of pumped liquid in 1 min will be important. On average, it is 25-50 l / min. At irrigation systems you can find twice as high indicators, which is due to the characteristics of the medium served. Technical fluids in the form of oils have a viscous consistency, while water has a lower load on the unit and thereby provides a large throughput. As for the engine power indicators, the barrel electric pump can be equipped with motors of 500-800 watts. The temperature characteristics of the medium served are also important. In the standard, the maximum temperature can be 95 ° C. But this will already be determined by the materials of the holder body and the transfer pipes. The most resistant is considered a combination of stainless steel and polypropylene.
Installation of a barrel pump
Before using the device, you should check its condition, engine performance, quality of connections and fasteners. Then the installation is carried out according to the following instructions:
- The target tank and pump are alerted. Connecting to the network.
- The suction tube is placed in the tank.
- A flexible drain hose with connected (if provided by the device) sensors and floats is introduced into the medium to be pumped.
- The outlet fitting is fixed in a vertical position using special clamps.
- The level positions of the two tanks are adjusted so that the device can provide stable pumping. It is especially important to observe this rule in relation to electric barrel oil pumps, pumping of which will require more energy resources.
- The system is started through a switch or a special button, after which the unit starts automatic operation.
- It is necessary to stop the process until the pumped liquid runs dry to the position of the intake suction device.
Barrel pump manufacturers reviews
The segment of aggregates of this type is rather narrow, and yet many domestic manufacturers are represented in it. For example, many praise the products of DEBEM, which offers the universal TR – EL model on AISI 316 steel alloy. As noted in practice, the device stably pumps liquids of various types from barrels, containers, tanks and other containers at a speed of 80–90 l / min . A positive impression is also caused by the barrel electric pump of the BERKUT brand. Particularly noteworthy is the modification of SMART POWER SP810EP, which is used in the professional field. The advantages of this version include a high level of electrical protection of the pumping circuit and the durability of the materials of manufacture. Among foreign manufacturers, JTC, NORDBERG and LIQUI MOLY products are noted. But such pumps are much more expensive.
Conclusion
The electrical power of the pumps greatly facilitates the process of pumping process fluids, saving people from unnecessary efforts. However, this same principle of operation makes it more thorough to organize protection with grounding and grounding of conductors. Also, do not forget that the operation of an electric barrel pump during long sessions will cost a lot. Power up to 1000 W, provided that even a small car service station can be serviced by several oil transfer circuits, can provide a tangible item in financial costs. Therefore, the selection of such pumps should be approached carefully, comparing the performance requirements with the energy potential of the equipment.
