A method of installing an annular bearing element within a centrifugal pump utilizes a mechanical staking operation. The bearing element locates within a receptacle of a pump stage that is surrounded by a retaining wall. Once the bearing element is located within the retaining wall, the retaining wall is permanently deformed at various points against the bearing element. The bearing element, if of a hard wear resistant metal, may have flats for the circumferentially spaced apart deformations to locate within. The bearing element may be a thrust washer for transmitting downward thrust, or it may be a radial support bearing sleeve.

An infrared welding system for joining two parts (PI, P2) made of thermoplastic material comprises a pair of infrared heaters (11, 11) for heating the two parts (PI, P2) while spaced from each other;and energizing the infrared heaters (11, 11) to emit infrared heat and directing the emitted infrared heat onto selected portions (Pla, P2a) of the opposed surfaces of the parts (PI, P2) to melt at least portions of the opposed surfaces, while directing an inert gas onto the selected portions to prevent ignition of the melted thermoplastic material. The two parts (PI, P2) are clamped together by moving at least one of the parts toward the other part to press the melted surfaces of the parts (PI, P2) into contact with each other. The parts (PI, P2) are cooled while they remain clamped togetherto solidify the molten thermoplastic material and thus weld the two parts (PI, P2) together.

A staking system includes a multifaceted support, each of the faces including a separate aperture to allow a stake to mount therethrough at varying angles. The support may be made of two separable elements. A bail is hingedly mounted in the support and set between various positions over the top of the support. A puller can be used to cause lever-action removal of the stake from the ground, and the pullet may be adjected to various distances. The support may be rotated along the ground surface to provide better attack angles for the lever-actuated removal.
