impeller are exposed to very strong loads. This can shorten the life span extremely. Further the operation of the
impeller pump loaded in waters with a high portion of suspended matters. The use of the impeller pump is particu-
larly critical in coral waterbodies. Cases are well-known, which a impeller pump had so strongly run after 100 hours
already that the lip seal on the wave was ground in. In these cases sharp crystal parts of the coral sand assess in the
rubber seal and affect like an abrasive the high-grade steel shank of the impeller pump. If the generator were moun-
ted over the water level it is particularly unfavorable for the impeller pump. After the first start some seconds will pass
by, until the impeller can suck in cooling water. This short unlubricated operation time damages the impeller. The
increased wear can lead after short time to the loss. (see special notes: "Effects on the impeller pump, if the genera-
tor is mounted over the waterline")
