Disclosed is side liner for a centrifugal pump. The side liner comprises an aperture for access to a central chamber of the centrifugal pump through the side liner. The side liner also comprises a plurality of grooves on a surface contacting material pumped by the centrifugal pump, the plurality of grooves extending radially from an inner edge of the surface, located near the aperture, to an outer edge.

Grooved side liner for centrifugal pump

A centrifugal slurry pump impeller including: a back shroud with opposed inner and outer faces and an outer peripheral edge, a central axis, a plurality of pumping vanes extending from the inner main face of the back shroud, the pumping vanes being disposed in spaced apart relation, each pumping vane including opposed main side faces, a leading edge in the region of the central axis and a trailing edge in the region of the outer peripheral edge of the back shroud with passageways between adjacent pumping vanes, wherein the inner main face of the back shroud along the length of the passageways, leading from the leading edge to the trailing edge, includes a generally planar inner region beginning adjacent the leading edge of the plurality of pumping vanes, and an outer region ending at the outer peripheral edge of the back shroud, wherein the outer region of the inner face of the back shroud includes a lip formation with an apex including a convex surface.

A sensing device for a centrifugal slurry pump having an impeller which rotates about an axis, the centrifugal slurry pump including a side liner and a main liner housed within an outer casing of the pump, the sensing device comprising; a body portion arranged to pass through the outer casing, wherein the body portion includes a sensor biased towards contact with either the side liner or the main liner of the pump.

Sensing device, system and method for a pump

A distributor device for use with cyclone separator apparatus, the distributor device comprising, a main body having a distribution chamber therein, the main body including a back wall and a front wall which at least in part enclose the distribution chamber, the main body including a peripheral region between the front and back walls, the device comprising a plurality of delivery outlets arranged in spaced apart relation around the peripheral region the front wall having an inner face and a back wall having an inner face, the device further including a feed inlet to the distribution chamber in the front wall having a main axis extending in a direction between the front and back walls; the back wall having an inner face which includes main face section and a protrusion which extends from the main face section towards the inner face of the front wall.

Distributor device for cyclone separator apparatus

A coupling pin for use in a pump housing, the pump housing including an outer casing and an inner pump liner, the coupling pin being suitable for locating the liner and casing relative to one another, the coupling pin including a shank and a head at one end of the shank. The head includes a cammed surface thereon which is adapted to co-operate with a follower on the liner, and a locating section on a remote or terminal end of the head which is adapted to be positioned against a seat in the outer casing when fitted. The arrangement is such that rotation of the coupling pin causes the follower to track along the cammed surface so as to cause relative movement between the outer casing and the inner pump liner.

Liner coupling pin

A slurry pump impeller which includes a front shroud and a back shroud each having an inner main face with an outer peripheral edge and a central axis, a plurality of pumping vanes extending between the inner main faces of the shrouds, the pumping vanes being disposed in spaced apart relation. Each pumping vane includes a leading edge in the region of the central axis and a trailing edge in the region of the outer peripheral edges of the shrouds with a passageway between adjacent pumping vanes. Each passageway has associated therewith a discharge guide vane, each discharge guide vane being disposed within a respective passageway and located closer to one or the other of the pumping vanes and projecting from the inner main face of at least one of the or each shrouds.

Slurry pump impeller

A pump casing for a centrifugal pump, which comprises an inlet opening, a discharge outlet, and a transition surface extending between an inner peripheral surface of the main pumping chamber and an inner peripheral surface of the discharge outlet, the transition surface arranged for separating an in use exit flow of material in the discharge outlet from an in use recirculation flow of material in the main pumping chamber. The transition surface has a cutwater having a profiled section which comprises a protrusion which extends irregularly from an otherwise generally rounded arched or U-shaped transition surface and is configured such that, in use, the velocity and/or turbulence resulting from the in use flow of the material being pumped in the main pumping chamber is reduced.
