the motor and what is the pump?
Lingo can be confusing.
Actually the "motor" only refers to the part that makes
the "pump" turn. It's the electronic part of the two.
Typically the motor is called a "motor" and the pump is
called the "wet end" and the pump and motor together is
called the pump/motor complete. Sort of obvious when you
think of it.
Important is matching the pump and motor?
Think of it like putting a small engine in a big car. It
might last but not long. OR, a big engine in a small
car. Wasted power. So engineers match the pump with the
motor. Too often a person will think themselves cleaver
putting a larger impeller on a pump and thinking they
are getting more power for a cheaper price. Again, you
can put a small engine in a car and pull a trailer with
it thinking those guys with a truck and big engine are
losers. They are not and you will be.
Circulation pumps are complete and
you have to replace the pump/motor complete.
Standard size pumps are replaceable
with your keeping the old motor. Replacement is easy. You can find
individual replacement parts but we only offer the complete pump.
Our activity in the field proves that replacing individual parts
often require replacing more parts rather quickly. We like the
shotgun repair on this to solve the matter without repeating service
The two most common pumps are 2hp and
3hp. We can special order any size but these are the most common.
Most Gatsby Spas have a small
circulation pump located to the right of the control box and pulls
water from the filter and forces it through the heater. This
circulation pump operates most of the time with some spas having a
summer shutoff to avoid overheating the spa. There are only 2
choices for circulation pumps: 110v and 220v pumps. They look
identical and the ID plate on the motor will ID which you have.
Some spas combine the #1 pump with
the circ pump. Those pumps/motors are 2 speed. They usually sit
behind the control box and are a standard size motor.
Your spa is probably one of four
a. One circ pump and a second larger
pump that is 1 or 2 speed.
b. One 2 speed pump.
c. One 2 speed pump and one single
d. One circ pump and two single speed
pumps. (most common)
Once you ID which you have and know
the voltage, replacement is easy.
What is a
frame? Motors are made to
match with a certain design pump. Usually a pump for one
frame will not match a motor of another. Some
manufacturers have made pumps that match a multiple
frames. There is also an aligning issue. Be careful you
get a matched frame.
my motor have 120v and 240v?
It is common for motor manufacturer to offer a motor
that is field wired. This means the motor can be wired
several ways and the installer can match
the motor to his application. Doing so usually means a
costlier motor but easier motor to obtain since one
motor will have several applications.
says "110vac" and another "120vac". Which do I need?
Electronics are built to cover
a range of voltages. Ideal in the U.S. is 120vac or
240vac. But most items are made to cover a +/- 10%. This
means that 110vac-130vac or 220vac-260vac is acceptable.
Most electrical providers provide close to the optimum
value or 120vac/240vac.
should a motor last?
That is a real good question. Usually 240vac motors last
longer than 120vac motors. They run more efficiently.
Often to make the spa readily available to the end user,
some spas are designed to run on 120vac or 240vac. This
is a plug-in spa. The motor on these will typically last
3-5 years. If have seen them last less and more. But
that is a good average to expect. Even if you can
upgrade the spa to 240vac, the motor will stay 120vac.
Spas that are ONLY operational on
240vac have longer lasting motors. The typical short
life is 5 years and many get longer. Motors that are
only operated when on HIGH can last the life of the spa.
Many times the thing that causes the HIGH pump to fail
is poor water quality has damaged the seal and it leaks
into the winding of the motor.
