1/3 HP has a double non-mechanical rubber lip seal. All ½ HP and above have double mechanical seals, with the upper seal made of NBR fitted carbon/ceramic, and lower seal made of Viton fitted silicon carbide/silicon carbide seals.

No -- All pumps are made of 300 series except for the 1/3 HP EPPD model which has a plastic Noryl impeller. The other 1/3 HP model and all ½ HP and above models are made of 300 series stainless steel.

140°F (60°C) intermittent operation and 122°F (50°C) continuous duty.

3/8"

Yes -- The Model EPD/EPPD is made with a permanent split capacitor motor. The benefit is the permanent split capacitor units draw about half the amperage of a shaded pole motor.

No -- All of these units are air filled which eliminates any problems with oil leaking out due to a mechanical seal failure. These pumps do contain approximately a tablespoon of mineral oil, located in the mechanical seal chamber to help lubricate the seal on start up.

Class F

Yes --
Single phase: through ¾ HP
Three phase: 1 ½ HP

No -- The Ebara float switch is a mechanical float switch eliminating any mercury contamination due to float switch failure.

1/3 HP units: 1 ¼" NPT discharge
½ HP and above units: 1 ½" NPT discharge.

Yes -- except the EPPD model that has the plastic Noryl impeller

The single phase pumps have built-in overload protection. Three phase models need overload protection supplied (supply your own).

The model EPD/EPPD is rated for 20 starts per hour.

1/3 HP = 5'
½ HP = 10'
¾ HP = 13'
1 HP = 15'
1 ½ HP = 16'

The suction MUST be completely under water if running the pump intermittently, minimu liquid level to be 3" above the floor. If running continuously, it is recommended you completely submerge the pump.

Flows: from 5 to 38 GPM
Heads: from 5 to 551 ft

Yes -- Automatic units are available through ¾ HP and manual units are available through 1½ HP
