Discharge casing

③

Middle casing

Motor

⑤

Common bed

⑥

Shaft coupling

This coupling connects the pump and motor
shafts, transmitting the motive power.

It absorbs misalignment between the shaft
centers.

⑦

Shaft coupling protective cover

⑧

Shaft seal part

Consisting of gland packing, it prevents water

leakage from the shaft penetrating hole.

The seal is a mechanical seal for MTP/MTP-e.

⑨

Air releasing valve

Air is expelled through the valve during

self-priming.

⑩

Priming cock

Warning

Be sure to put a shaft coupling protective cover
during operation. Failure to observe this may
lead to an injury or damage.

SP(3)/SP(3)-e, MSP/MSP-e
