1. PC shielded muting circulating pump (hereinafter called as "electronic pump").
The motor stator will be totally shielded and the rotary components will emerge
into clean water, playing an important role in cooling and lubricating during working:
the thin housing structure is used as pump shielded sleeve, which fully separates
the inner core and external water. It also cancels the traditional mechanicalsealing
structure and successfully solves the common leakage, the rotary components are
adopted on ceramic bearing, which is durable and can be purified with clean water.
Ceramic bearing can not only effectively cool the motor, but also reduce the noise,
and guarantee no overload during all the working process. This product is able to
be free of service if accurately used.
2. There're three-grades settings on switch knob of junction box for speed adjusting
and the flow and total head change. Grade I is low speed with min flow and head;
Grade II is intermediate speed; Grade III is the rated speed. That is, high speed with
max flow and total head.
3. Heat- proof material is adopted in inner motor avaliable for heat circulating com-
pression system.
