Product Description
1. Manufacturing overview
7121 Sequence micro diaphragm pump is a new module that independently created by
Keyto. Its main perform is diaphragm reciprocating by motor operates. This collection is vast utilized
in health care instruments, environmental security products, meters, chemistry equipment,
home electrical, laboratory instruments and other CZPT d location.
one.1 Attributes of 7121- series diaphragm pump:
The principal of diaphragm pump is the elastic diaphragm reciprocating by centrifugal
wheel
rotating, to alter the volume of chamber. And we designed single path poppets at input
and output port, to attain medium aspiration and dispensing.
Characteristics:
1) Offer pure liquid transportation and fuel aspirate atmosphere.
two) Oilless, maintenance free, CZPT lifetime
three) Tiny vibration, low noise
four) CZPT sealing, corrosion resistance
five) Easy to assemble.

This vacuum pump is created for deeper vacuums down to seventy five microns. Precision machined primary pumps take away humidity from air conditioning techniques for secure refrigerant addition. This solitary-stage vacuum pump is best for automotive air conditioning, HVAC work, and other operations that call for a large vacuum from a compact pump. Very first stage vacuum to 75 microns Sturdy die-solid aluminum housing and convenient best handle Easy to use
