Speck 21-80 G/GS Pump Power End, 4.0 HP, Single Phase
Power end for the 4 HP Speck 21-80.
This Speck power end is the 4.0 HP, single phase, single speed power end for the Speck Model 21-80 G (flooded suction) and Model 21-80 GS (self-priming) pumps, on a 56C frame. Speck lists its 4.0 HP versions as Models 21-80/33 G and 21-80/33 GS, rated 208-230 V. Speck designs the 21-80 so the motor comes out without disturbing the plumbing.
Why PST Customers Pick This
Fits the 21-80 G and GS
Listed for both versions of the Speck 21-80: the 21-80 G flooded suction pump and the 21-80 GS self-priming pump, which Speck rates for self-priming up to 4 feet.
4.0 HP Single Phase
A 4.0 HP, single phase, single speed power end on a 56C frame. Speck lists its 4.0 HP 21-80/33 G and GS at 208-230 V, 21.0 to 19.4 A, 5.0 total HP and a 1.25 service factor.
Energy Efficient 56 Frame Motor
Speck builds the 21-80 on heavy duty "1081" E-plus / extreme-E energy efficient pool motors: a large 56 frame motor, thermally protected, with a PSC switchless design and extra large sealed ball bearings. No motor starter is required.
Swaps Without Re-Plumbing
Speck notes the 21-80 motor is easy to remove without disturbing the plumbing, with reusable O-rings throughout. Its manual describes removing the eight casing bolts at the aluminum flange and sliding the motor out with the seal housing.
Seal Parts for the Job
Speck lists the 21-80 mechanical seal as 2920343310 (20 mm, carbon/ceramic) and the SPK-2180-GOKIT Seal GoKit, which includes the mechanical seal, O-rings, gaskets and V-ring.
Built for Pool Water
Speck rates the 21-80 for pool water with up to 5,000 ppm salt and temperatures up to 175°F, and its impeller has a dielectric shaft sleeve that separates pool water from the electrical parts.
Installation Notice
Speck states that the 21-80 must be installed and serviced by a qualified pool professional and conform to all national, state and local codes. It must be connected to a GFCI-protected supply circuit, and the motor must be bonded per NEC 680-26 using the copper bonding lug.

This costume is legit. It has the sparkle, glittery sheen to it like the one used on screen! Very happy with it!!
Excellent service!
PST was great at communicating the status of my order throughout the various stages. I actually did encounter a shipment issue and they handled it without issue. I will be doing business again with them.

as described, fast shipping
My wife has RA and is always uncomfortable. Our hot tub heater failed and all the local shops were not able to assist until November. I was able to order an exact replacement part which was delivered within 3 days the hot tub was up and functioning in three days. I was very impressed with the quality and service.
Good quality just ordered wrong size and also need thicker cover
Fit perfectly, and fast shipping
Super fast shipping and reliable product !
I accidentally broke the original **** by tightening it too much. This was a perfect fit and works 100%. Fast delivery too!
Swapped out broken heater (lasted about 6 years) for this one. The instructions are for the electronics, not for the plumbing. You must get everything perfectly aligned or the plumbing may leak. I needed to loosen the electronics box to get the plumbing perfectly aligned. I have hot water again.
Great prices, fast shipping, great products
Haven't received yet but I'm sure it'll be great
Ordered on Saturday and we're delivered by Tuesday! Great products and great prices!
PST pool supplies are great to work with. I was having trouble finding this heat exchanger . Everywhere I looked, it was out of stock or back ordered. I contacted the manufacturer about buying the heat exchanger. They told me I couldn't buy it because I wasn't a dealer. If I was a dealer, they would be able to take the order. And make one, it would take 5 to 8 weeks. I contacted PST they put my order in and I received it in about six weeks. Fantastic people to work with. Thanks Tim
