Problems solved by technology

[0005] Currently, the pumps used to pump such solid emulsions and liquid explosives are larger in size and more complex in design, making them inconvenient and expensive to use in conjunction with solid emulsions and liquid explosives, and this limits the application to what is available for this purpose Cases where there is sufficient space for larger pumps

Embodiment Construction

[0045] When, the terms "front" and "back / rear" should be understood as referring to the axis of the shaft 8 in the accompanying drawings, and the terms "left" and "right" should be understood as referring to the axis of the shaft 8 in the accompanying drawings. rear (basically in the figure 1 right-hand side) to the front (basically in the figure 1 The left-hand side of the) when viewed with respect to the axis of shaft 8, thus, in figure 1 The parts of the pump on the side closer to the observer with respect to the axis 8 are on the "left" side, while on the figure 1 The parts of the pump on the side of the axis 8 farther from the observer are located on the "right" side.

[0046] figure 1 The entire rotary displacement pump 2 is shown, comprising a pump part 4 or pump body 4 and a support part 6 .

[0047] exist figure 1 On the right-hand side of , the end of the shaft 8 protrudes from the support part 6 . A not shown drive motor, typically an electric motor, is used t...

Abstract

A rotary displacement pump of an undulatory disk type; with a pump housing (24) comprising a front end plate (56) and a rear end plate, the pump housing enclosing a stator (40, 48), a rotor (42), a scraper (44) and a scraper guide (46), a shaft (8) extending through at least the rear end plate; the stator including a generally semi-circular arc-formed first stator member (40) and a generally semi-circular arc-formed second stator member (48), the stator, the pump housing and the scraper together with the scraper guide defining an inlet and outlet chamber, wherein at least part of the end faces of the first and second stator members being situated in the outlet chamber are oblique so as to provide an obtuse-angled transition to the inner faces of the front end plate and the rear end plate.

Description

technical field [0001] The present application relates to a rotary displacement pump for pumping solid-containing emulsions, especially liquid explosives. Background technique [0002] A rotary displacement pump is known from EP1807624B1 which allows the pumping of flowable, relatively viscous materials in the food industry, the chemical and biochemical industry, the pharmaceutical industry and the cosmetics industry. Examples of materials that can be pumped with such a rotary displacement pump are yogurt, soups, sauces, mayonnaise, fruit juices, cheese ingredients, chocolate, paints, cosmetic creams and lipstick ingredients. [0003] There exists a need to pump solids-containing emulsions, especially liquid explosives. Such liquid explosives are used, for example, in the mining industry and in quarry operations in the field of tunnels, where the liquid explosive has to be pumped into cavities and channels in the rock where it is detonated, thereby producing Explosion in a...
