The invention relates to a technique of pump engineering, in particular to the special devices for safe mechanized pumping various types of liquid media with different viscosity, Flammability, aggressiveness, and can be used in industries with high fire danger for pumping liquids as from the process container having a neck with an internal thread or without thread, for example metal 220-280 litre drums, and from the process container having a neck with an external thread, such as a plastic canisters and jars. The invention can find wide application in food, pharmaceutical, chemical and petrochemical industry, electroplating plants and in plant chemical laboratories, storage farms, and various workshops.

Known hand piston pump with a muscular drive, in particular for pumping oil from barrels having a neck with an internal thread or without thread containing the receiving tube, the piston and rod, and a knob on the end for vertical reciprocating movements (bodybuilder) and a fixture for fixing a receiving tube manual on it by means of two Cam levers, pivotally mounted on the clutch housing and connected to each other by the clamp, thus to enable fastening of the pump in the holes, no cuts, tapered coupler has at the end of the frame, in which is located an elastic o-ring seal that presses the Cam lever to the inner surface of the neck.(see and. C. the USSR № 227101, IPC F 05, B 67 d, publ. 16.09.1968, bull. No. 29).

Its disadvantages include low productivity, low security, narrow scope, complexity and lack of reliability of technical means of implementing the known device in relation to the different types used in the production of containers and different types of the liquids being pumped.

Low productivity of manual pump due to the fact that during each working cycle in the pipe rises only a small amount of liquid equal to or less than the volume of the internal cavity of the piston, and only when the movement of the piston and a part of a liquid spill or uneven movement of the piston. Low security of the pumping process pump of this design is that part of the liquid (about 5%) is sprayed in different Stamou fluid at least 95%, as before emptying the container the pump piston begins to beat on the bottom of the container will either not reach the bottom, which is defined as a structurally depth rod. The narrow scope and low technological capabilities do not allow for safe handling of aggressive liquids from glass bottles or plastic flasks and containers having a neck with an external thread.

It is also known a device for filling aggressive liquids - URA (see information sheet NPC “Vector”), which contains a rubber conical plug mounted with tension in the neck of the bottles (cans) to achieve integrity, one end of the draught tube is immersed in the liquid, and the free end of the draught tube is lowered into the vessel for pumping fluid. With the help of the pump (“gently push on the pump-pump”) is supplied compressed air through the nozzle device in the pressurized cavity with the fluid, after which begins a free overflow, stop by pressing the button of the valve”.

The disadvantages of this device are low productivity, lack of security, the narrow scope and low technological vozmojnostyami in the manufacture of containers and different types of the liquids being pumped.

Low productivity and security, and low technological capabilities of this design can be explained by several reasons:

- due to the lack of valve discharge occur at every new “rolling” three-dimensional loss of compressed air from the pumping cavity on the suction phase of a new portion of air from the atmosphere;

- due to the lack of valve regulating the fluid constantly at each operation for pumping liquid portion to forcibly pull the excess pressure of the injection cavity into the atmosphere to stop overflow;

- due to the lack of valve regulating the amount specified for each processing operation the excess pressure in the pressurized cavity, always have to “pump” to pump compressed air is injected in the cavity (despite the loss), and in this case there is only a free flow of fluid by gravity;

- due to the lack of valve regulation (and taking into account security and control valve) it is impossible to create a pressure in the pressurized cavity, so that it is possible, for example, to pump concentrated hydrochloric acid 38%, having a density of 1.19 kg/cm2

- when trying to create a little more excessive pressure pulls plug the bottom of the air pump, which again is associated with a significant leakage of compressed air from the inlet cavity and the absence of a discharge valve, rubber pump “frog” is inflated.

In addition, it is also possible departure conical tube from the neck of the container when you create a little more pressure, making it unsafe for pumping aggressive liquids as hazardous even facing pair of concentrated acids or the smallest particles (spray) fluid, which can cause various body burns or burns of light” at the mere inhalation of the vapor of the acid.

The closest to the essential features of the device of the same purposes of the claimed invention is a pump for pumping aggressive liquids adopted for the prototype, which contains a pneumatic pump with a muscular drive, forcing a cavity which is connected to the atmosphere through valve suction hose compressed air from the pump in the injection cavity technological containers with the pumped liquid, technological nozzle with clamp installed in the neck of the container to another in the shoulder, which is LAPAN excess pressure into the atmosphere, and another fixed a cold pipe, dipped one end into the liquid to be pumped, a clamp for tight fastening of the insert in the neck of the container (see “journal of Currency production and technical experience”, vol.7, 1986, S. 38); see also prospect research-and-production company “Ecros”laboratory of the XXI century, vol. 10 “Laboratory equipment and instruments 2001 Pumping system PE-3000, PE-3010, S. 39).

For reasons that impede the achievement of specified following technical result, should include narrow scope, low productivity, lack of security and low technological capabilities technical means. Low productivity due to the fact that the process of pumping fluid from the process of Tara pump of this design is constantly interrupted due to a forced descent excess pressure into the atmosphere, so with each new technological operation pumping portion of the fluid is again pumped compressed air is injected in the cavity, and this requires a certain time. For example, to create the desired excess pressure in the pressurized cavity of the container to displace the fluid, you must: 1)when pumping ito corresponds with 6-7; 2) when pumping from 220-280-liter metal drums to perform within 18-25 of bodybuilder pump, which corresponds 27-38 (depending on the volume of the pressurizing cavity of the container).

These drawbacks are due to the inability to provide for the pumping of corrosive liquids from containers installed on the floor and feed them to the height of the working area, for example, etching installation or high galvanic baths, and lack of security when pumping highly “floating” poisonous liquids (acids, ammonia, acetone, formaldehyde, gasoline, hydrogen peroxide, etc.,) due to the lack of faucet flow control, valve, discharge of compressed air, valve, regulating excessive pressure in the pressurized cavity, a protective casing with a nozzle connected to a flexible tube with exhaust ventilation. The narrow scope due to inability to use the pump for pumping liquids from the process container having a neck with an internal thread or without thread and, in addition, the inability to provide for the regulation of supply of the fluid to ensure its volume measured flood in vessels of small capacity.
