This Kit is an 4HP Impeller for an Executive 48 Frame Wet End up to 4HP Motor and a 56 Frame Wet End 4HP Motor. This Impeller fits between the Face and the Volute of an Executive Wet End. I would advise replacing the Seal when you replace the Impeller. We offer a Seal, Silicone and Impeller individually or in a kit, and the Purpose of this Kit is to repair a Damaged Impeller and Seal inside the Wet End. This is (1) Impeller ONLY!!
NOTE: A 4HP Impeller can be found on motors that are 12-14 Amps at 230V on high speed one way to determine is to look at the wear ring.. If the ring says 1,2 & 3 you choose a 3HP it if says 4 or 5 you choose a 4HP..
Note: A 230V motor that would use a 4HP would show about 12.0-14.0 Amps on High. See chart below for other Horsepowers.
Do Not choose a Larger Impeller thinking that it will make your Hot Tub Stronger it will only damage the Motor and make it run hot on high speed.
Note: There is usually a Horse Power Stamped into the center of the impeller for 2HP, 3HP and 4HP.. (See the picture example) 1HP and 5HP usually don’t have a stamp so you would determine those by the Amperage Chart..
To determine the HP refer to the chart below..
The difference between a 48 or 56 Frame wet end is the spacing of the Motor Thru bolts.
The 48 Frame will be 3 5/8" between or 5 3/16" in a X Pattern and the 56 Frame will be 4 1/8" Between or 5 3/4" in a X Pattern.
You must go by the Amperage Sticker on the motor not stickers on the Wet End or Motor especially the BHP Stickers.
Look on the label of the motor for the two amperages if you have a 2 speed pump or if its a single speed look for a single amperage. An example will look something like this: 10.0/3.5 The 10.0 is the high amperage in this example.
115V Chart Below
3/4HP 8-9 Amps
1HP 11-12 Amps
1.5HP 16-17 Amps
2HP 19-20 Amps. 2HP would be very rare.
230V Chart Below
8.0 = 1 HP
10.0 = 2 HP
12.0 = 3 HP
14.0 = 4 HP
16.0 = 5 HP
NOTE: Your pump or motor may say a different Horse Power than what you see here, DO NOT go by what is listed on the motor, go by the amperage on the label.
NOTE for the NOTE: TRUST ME ON THIS, everybody lies about their Horse Power. But the amperage does not lie. Most people are told incorrectly that they have 5 HP pumps.
If you do the math two 230V 5 HP pumps at 16 amps is: 32 amps. Plus a 5.5 KW heater is: + 21 amps.
That means with both pumps running and the heater on it will draw = 53 AMPS.
I bet your HOT TUB is on a 50 AMP breaker…... Therefore contrary to what you have been told you DO NOT have a 5 or 6 or 7 Hp pump.
