A conveying device for conveying a viscous material from a container includes a follower plate that can be inserted into the container, and a pump by means of which the viscous material can be conveyed through the follower plate. Moreover, a measuring chamber for accommodation of a measuring sample of the viscous material is provided. The measuring chamber includes a closable material inlet opening for this purpose. A closable disposal line leads away from the measuring chamber. Moreover, a closable material return line extends from the measuring chamber via the follower plate into the container. The conveying device also includes a controller that is designed and can be operated appropriately such that it determines the compressibility of each of multiple measuring samples. The controller opens the disposal line or the material return line to the measuring sample present in the measuring chamber as a function of the compressibility thus determined.

A pump follower for use in a container storing a material includes a body configured to be inserted into the container, the body having a material contacting surface configured to contact the material in the container and a peripheral surface substantially perpendicular to the material contacting surface. A groove is defined on the peripheral surface of the body and a sealing element is disposed in the groove and configured to slidably contact the container. The sealing element has a channel defined within, where the sealing element is configured to be compressed when the pump follower is inserted into the container, such that the channel decreases in size. A sealing element for use with a pump follower is also disclosed. The sealing element has a body has an outer surface, a first side, and a second side, and a channel defined within the sealing element body.

A drum unloader may include a pump assembly, a motor, a plate, a piston-cylinder assembly, and a sensor. The motor drives the pump assembly. The plate is mounted to the pump assembly and includes an inlet to the pump assembly. The piston-cylinder assembly includes a housing, a piston, and a piston rod. The housing defines a bore. The piston is received within the bore and cooperates with the housing to define a first cavity and a second cavity. The piston rod is attached to and extends from the piston such that the piston rod extends through the first cavity. The piston rod is coupled to the pump assembly, the motor and the plate such that movement of the piston within the bore causes corresponding movement of the pump assembly, the motor and the plate relative to the housing. The sensor measures a pressure within the second cavity.

An emptying system for emptying paste-like material from barrel-type containers having a container follower platewhich preferably can be lowered like a plunger into the interior of the containerand which includes a removal opening having a pump in operative connection with the removal opening for extracting material enclosed in the collection chamber between the container bottom and the container follower plate, wherein in the collection chamber at least one agitator is provided, which imposes on the material contained in the collection chamber a motion in relation to the container follower plate.

The invention relates to a device (2) for sealing and evacuating or applying gas pressure to a paste-like liquid in a container, the interior chamber thereof having a cylindrical inner contour (12). Said device comprises: a seal (8) which is arranged on a circumference of the device (2) and is adapted to be inserted into the cylindrical inner contour (12) of a container in order to seal the circumference of said container, and which delimits the exterior (18) of the device (2) from the interior (20) of the device; a connection device (22) which is arranged on the exterior (18) of the device (2) and which is configured for connecting an evacuation pump; and an open-pored, porous wall (24) in the interior of the device (2), said wall having a conduit connection (25) to the connection device (22).

A drum unloader may include a pump assembly, a motor, a plate, a piston-cylinder assembly, and a sensor. The motor drives the pump assembly. The plate is mounted to the pump assembly and includes an inlet to the pump assembly. The piston-cylinder assembly includes a housing, a piston, and a piston rod. The housing defines a bore. The piston is received within the bore and cooperates with the housing to define a first cavity and a second cavity. The piston rod is attached to and extends from the piston such that the piston rod extends through the first cavity. The piston rod is coupled to the pump assembly, the motor and the plate such that movement of the piston within the bore causes corresponding movement of the pump assembly, the motor and the plate relative to the housing. The sensor measures a pressure within the second cavity.

The invention relates to a container emptying device (1) for emptying at least one container (6) filled with a liquid, comprising a suction unit (2), a receiving unit (4) and a pipe unit (3) connecting the receiving unit (4) with the suction unit (2). The suction unit (2) comprises at least one suction lance (2a) adapted to be inserted and lowered into the container (6), at least one pump (2c), connecting the suction lance (2a) with the pipe unit (3), for pumping the liquid out of the container (6) and a control device for controlling a suction process. The pipe unit (3) comprises at least one flexible pipe for transporting the liquid out of the container (6).

The present invention relates to an electric grease barrel pump and, more particularly, to an electric grease barrel pump which is configured to supply an appropriate amount of grease to an attachment connected to a distribution valve by enabling an actuator of the distribution valve to operate in conjunction with and according to a change in the number of stages of a driving means.

A feeding device for a flowable material is provided with a platen housed in a container containing the flowable material, a cylindrical ram attached to the platen, a pump that reciprocates a piston housed in the ram to suck up the flowable material in the container and a determination device configured to determine a replacement time of the container based on a change in a moving speed of the piston.

An apparatus for conveying viscous material out of a barrel-like container having a container bottom and a container wall that extends upward from the container bottom has a follower plate for closing off the container, which plate is movable in the direction toward the container bottom, lying against the inner surface of the container wall, which surface faces the container interior, and which plate has a dome that extends upward from an underside intended to lie on the viscous material, which dome opens, in the center, into a material exit opening. The apparatus has a pump for conveying the viscous material through the material exit opening. At least one displacement body projects into the dome through the material exit opening and is connected with the pump for displacement of the material situated in the dome and/or air situated in the dome, and at least one closeable venting opening vents the dome.
