The pump image shows the pump discharge on top pointing to the 12 o'clock position. The pump discharge can also be rotated every 90-degrees (3, 6 or 9 o'clock positions) by loosing the four long bolts at the back of the motor. The pump intake (suction) is located in the front center face of the pump.

If buying this pump for retrofitting, add a pair of pump unions that connects to your pipes which then screws directly onto the pump threaded fittings. O-rings are included with the pump unions.

If buying this pump as an exact replacement that does not require retrofitting, it is highly recommended to replace the pump union o-rings at the same time. Old pump union o-rings may cause leaks that can damage the new pump and affect the warranty. O-rings for pump unions are only available with a pump union purchase.

You may add a cord to be attached to the motor at a discounted price. See cord options above.

The pump normally ships from the factory with the discharge pointing "UP" which is the standard position for shipping, but they can be turned or what is called "clocked" into any position (12, 3, 9 or 6 o'clock position). Rotation of the pump discharge can be done in the field, but we recommend having it performed by a professional spa technician who is experienced. Or choose the option to have the pump professionally rotated at the factory before it ships. This is to avoid water leaks and operational problems due to improper removal and installation in the field that will affect the warranty. As you face the front end of the pump wet end, available positions are 12 o'clock (Up), 3 o'clock (Right), 9 o'clock (Left), and 6 o'clock (Down, which is very rare).

This Viper-56 pump is a replacement option for the following pumps (Just match the amp rating to get the same performance pump): 3721621-1T, 3711621-0T, 5KCP49UN9096XVIPER, 1-00-0106, 3721621-0T7H, PV30-2N22C (Model; Must Verify Pump), 3711621-0T7N (Single Speed),

Keep in mind to not over power your spa by going from a 48-frame motor to a 56-frame motor.

This pump normally uses the following motor part numbers: 0-187563-02, R63MWENA-4727

The pump wet end will have the model numbers 311-1510 and 315-1500. Make sure to match amp rating.
