Wilden's Hornet™ pump is designed to meet the
performance requirements of even the most demanding
pumping applications.
the highest standards, this pump is well suited for general
commercial and industrial applications.
performance information in this manual for an in-depth
analysis of the performance of your pump.
HOSE CONNECTIONS: Use flexible suction and discharge
hose ONLY. This is done to avoid excess stress on the pump
port fittings. The suction hose size should be at least the
equivalent or larger than the diameter size of the suction inlet
on your pump. The suction hose must be non-collapsible,
reinforced type as these pumps are capable of a high
vacuum. Discharge hose should also be the equivalent or
larger than the diameter of the pump discharge which will
help to reduce friction losses. It is critical that all fittings
and connections are airtight or a reduction or loss of pump
suction capability will result.
Final determination of the pump site should not be made
until the piping challenges of each possible location
have been evaluated. The impact of current and future
installations should be considered ahead of time to
ensure that inadvertent restrictions are not created for any
remaining sites.
INSTALLATION:
Months of careful planning, study,
and selection efforts can result in unsatisfactory pump
performance if installation details are left to chance.
Premature failure and long term dissatisfaction can be
avoided if care is exercised throughout the installation
process.
For best results, the pump should use a 5μ (micron) air
filter, needle valve and regulator. The use of an air filter will
ensure that the majority of any pipeline contaminants will
be eliminated.
Pumps in service with a positive suction head are most
efficient when inlet pressure is limited to 0.5-0.7 bar (7-10
psig). Premature diaphragm failure may occur if positive
suction is 0.7 bar (10 psig) or higher.
Every pump location should have a gas supply line large
enough to supply the volume of gas necessary to achieve

maximum of 8.6 bar (125 psig).
LOCATION:
Noise, safety, and other logistical factors
usually dictate where equipment will be situated.
ELEVATION: Selecting a site that will be within the pump's
dynamic lift capability will assure that loss-of-prime issues
will be eliminated. In addition, pump efficiency can be
adversely affected if proper attention is not given to site
location.
ACCESS: The location should be accessible. If it's easy to
reach the pump, maintenance personnel will have an easier
time doing routine inspections and adjustments. Should
major repairs become necessary, ease of access can play a
key role in speeding the repair process and reducing total
downtime.
OpErATION: Pump discharge rates can be controlled by
limiting the volume and/or pressure of the gas supply to
the pump (preferred method). An air regulator is used
to regulate pressure. A needle valve is used to regulate
volume. Pump discharge rates can also be controlled by
throttling the pump discharge by partially closing a valve in
the discharge line of the pump. This action increases friction
loss which reduces flow rate. This is useful when the need
exists to control the pump from a remote location.
When the pump discharge pressure equals or exceeds
the gas supply pressure, the pump will stop; no bypass or
pressure relieve valve is needed, and pump damage will
not occur. The pump can be restarted by reducing the fluid
discharge pressure or increasing the inlet gas pressure.
The Wilden Hornet™ pump runs solely on clean-dry gas
and generates little heat. Therefore, your process fluid
temperature will not be affected.
SUBMErSIBLE AppLICATIONS: The Wilden Hornet™ pump
design is not suited for submersible applications.
WArNING: The Hornet™ pump is intended for use with
fluids having little or no particulates in the process media.
Excessive or large particulates in the process media will
adversely affect pump performance and service life.
