Pumps
Health
care equipment offers quality vacuum pumps
for
laboratory, industrial and educational applications.
May be
used for filtration, degassing, distillation, free
air displacement
and any other requirements where vacuum or positive
pressure
needs call for pumps of high quality. Exceptionally
durable
for continuous or intermitent use, these pumps serve
a variety
of needs.
Vacuum
Pumps, Single Stage DUOSEAL Belt-Driven, Welch
Pumps are ideal for continuous-duty applications,
including
vacuum distillations, glove box transfer chamber,
residue
solvent removal, and resin degassing. They feature
thermal
overload protection standard and operate at a low
rpm which
allows them to reach a low ultimate pressure (0.02
mm Hg).
Operating at low speed also reduces the rate of
friction and
wear on pump components which ensures a long service
life.
Vacuum Pumps, RV Dual-Mode, Direct Drive, BOC
Edwards
These
quiet, double stage vacuum pumps are designed
to provide
both high throughput and low ultimate vacuum.
Dual-mode action
allows user to easily configure the unit to pump a
very high
gas load or achieve an excellent vacuum, all from a
single
pump.
Features
include a cartridge-based pumping mechanism
incorporating
advanced new materials, fully featured Edwards
motor, and
fast acting inlet valve to seal the pump for
suck-back protection.
Controls are clearly marked and have easy-to-use
large finger
grips. On/off switch controls pump. Inlet/oulet
connections
are NW25.
Units
feature special dual voltage, dual frequency motor
with an
IEC main input socket. Shaft seal can be changed or
repositioned
without dismantling the pump. Motor voltage is
determined
by simple rocker switch, enabling pump to be easily
configured
for international use. For 115V, 50/60Hz operation.
Vacuum Pressure Pump, Gast
This
readily mounted unit produces steady, quiet,
pulseless air
delivery. It delivers 20 psi of pressure for
intermittent
service alternately and 15 psi pressure for
continuous service
alternately.
The
pump rotor is mounted on the motor shaft.
Composition vanes
take up their own wear automatically. Self-adjusting
shaft
seals prevent oil leakage. The motor is a 1/6hp
split phase,
with internal thermal protector, ball bearing-type.
Pump is
single phase, with automatic overload protection.
Vacuum
Pressure Pump
This
vacuum has an oil-less diaphragm pump. The motor is a
single
phase 1/8 hp shaded pole, ball bearing type, with
internal
thermal protector.
Oil-free Vacuum Pump Rocker 300/500
These
Pumps are undoubtedly the BEST VALUE offered in the
USA and
are backed by a two-year warranty.
Quiet
and Low Vibration
Directly motor driven without transmission mechanism
and quality
rubber feet keep noise level only 48.7~60dB, which
is the
lowest among equivalent products.
Compact
and Light Weight
Aluminum die-cast and precise construction make
Rocker's family
small and compact. Net/Gross Weight: 4.1/5.1kg.
Clean
and Maintenance Free
Oil-free design makes it clean and maintenance free,
we guarantee
two years or 3000 working hours of free service
parts (excluding
moisture filter).
Safe
and Comfortable
Rocker's family are CE approved, it not only
promises safety,
but also makes the operator feel comfortable.
