Kemet Portable Hand 3 Lap Kit for Lapping and Polishing

The Portable Hand 3 Lap Kit is admirably suited for ON SITE refurbishment. It contains three lapping plates, each with its own grade of Kemet Diamond Compound. This makes it possible to process components, e.g. valves and seals, in three stages from lapping through to polishing. Each lapping plate is backed with anti-slip matting.

Portable Concentric Grooving Lapping Kit

Hand lapping uses the same principles as machine lapping with respect to abrasive grade / plate selection / plate flatness, but with the following exceptions

  • Lapping plate is kept stationary
  • Components are moved by hand in a figure of 8 action
  • Diamond compounds or liquid diamond can be used

Leaking pumps, valves and seals cause many problems, leading to wastage, poor performance, unnecessary costs, even health hazards. Kemet Portable Lapping Kits enable refurbishment to be carried out on site, reducing expensive downtime. Components manufactured from ceramics, tungsten carbide, stellite, brass, steel, silicon carbide, carbon, ni-resist etc, can be lapped and/or polished by hand in minutes rather than hours. The kits are also ideal for low volume production, where it is not economical to purchase a lapping or polishing machine.

Carbon Mechanical Seals Lapping Kit

Kemet have developed a portable kit for dry lapping of carbon mechanical seals. The kit consists of a special Kemet lapping plate mounted onto an aluminium backing plate. The specially textured plate allows carbon seals to be lapped without the need for any added loose abrasive. This alleviates loose abrasive impregnation into the carbon face.

  • Kemet portable case for ease of transport
  • Consumables to maintain the condition of the lapping plate
  • Code: 352565
