Speroni APM 100 Deep suction pump

APPLICATIONS
Self-priming electric pumps for aspirations up to 35 meters deep, used whenever there are strong excursions in the water level. Suitable for water supply with suction from wells, for domestic use by means of small and medium-sized tanks (autoclave). Before installation, check that the pipes, (iron, plastic or rubber) are internally clean so as not to clog the ejector nozzle. A foot or check valve must be mounted on the ejector foot. When assembly is complete, completely fill pipes and pump body with clean water. To maintain an efficient priming it is necessary that there is a certain pressure in the circuit, so it is advisable to mount a diaphragm tank on the delivery of the pump.

LIMITS OF USE
- Liquid temperature up to 35 ° C
- Ambient temperature up to 40 ° C
- Manometric suction height up to 45 meters.
- Continuous service

MOTOR
- 2 pole induction electric motor (n = 2850 min-1)
- Class F insulation
- IP 44 protection

MATERIALS
- Cast iron pump body
- Aluminum motor support
- Noryl impeller
- Noryl diffuser
- Cast iron ejector
- Stainless steel holding flange
- Stainless steel motor shaft
- Ceramic / Graphite / NBR mechanical seals

» Data sheet

The separate ejector pump is basically a centrifuge, with the possibility of becoming a deep suction self-priming jet pump, with the application of the ejector, in the well, on the final part of the suction pipe.

The recirculation of the water that flows through the venturi attracts the underlying water and pushes it through the return pipe (suction) creating enough pressure to bring it to the surface.

For these deep suction applications, the connection of two pipes is necessary: The delivery to the ejector and the return (suction) discharge, in this case the diameter of the well must be at least 4 ".

If the pump is to be applied in a 2 "well, a" Jector "ejector with hermetic closure is required on the well, which works with only the return (suction) tube, taking advantage of the space that remains between it and the 2" well as second
recirculation tube.
