Self-priming System
Automatically eliminates air from suction piping — prime once, operate always.
Self-priming Centrifugal Pump PJm-100S
1 HP single-stage self-priming pump for residential, building and small irrigation use — suction up to 9m and 40m head
The Atlantis Self-priming Centrifugal Pump PJm-100S is designed for residential and building use, serving small irrigation and light industrial applications — ideal for wells, cisterns and low-pressure networks.
The self-priming system removes air from the suction piping automatically, eliminating the need for constant pre-filling with water — just one initial priming during installation.
With high suction up to 9 meters and maximum head of 40 mca at peak pressure, the PJm-100S solves weak water supply problems in buildings up to 6 floors, houses with elevated water tanks and pressurization systems.

Installation Guide
Follow the guidelines below as a general reference.
1
Before installation, ensure the pump is properly grounded according to safety standards (NBR 5410).
2
Install the pump vertically in a dry, ventilated location protected from rain and splashes. NEVER submerge in water.
3
Connect 1" suction piping to the inlet and 1" discharge piping to the outlet.
4
Initial priming: fill the pump and suction piping with water before first start. Subsequent starts are automatic.
5
Connect to the correct voltage (127V or 220V depending on model) and install a compatible breaker with RCD protection.
Important tips
- Mandatory grounding: before operating, ensure the pump is properly grounded according to electrical safety standards.
- NEVER touch the pump while it is operating. Risk of electric shock and burns from natural heating.
- DO NOT run the pump dry. Operating without water immediately damages the impeller and motor — voids warranty.
- Protect the motor from rain and direct splashes. Despite IP44, prolonged water exposure can cause electrical damage.

Frequently Asked Questions
Common questions about specification, installation, and use.
It is a pump that combines centrifugal system (high flow) with self-priming capability — it has an internal diffuser that automatically eliminates air from suction piping, eliminating manual re-priming at every start. You prime once during installation and the pump maintains suction on its own.
The PJm-100S has 1 HP (750W), 2,900 L/h flow and 40m head, ideal for larger residences, buildings up to 6 floors and small irrigation. The PJm-60S has 1/2 HP (370W), 2,100 L/h flow and lower head, ideal for apartments, compact homes and lighter applications. Both versions are available in 127V and 220V.
Yes — one of the main applications. The PJm-100S has high suction up to 9 meters, sufficient for most cistern wells and shallow wells. For deeper artesian wells (over 9m), we recommend Atlantis submersible pumps. Remember to install the pump above the well level, NEVER submerged in water.
NO — this is the main advantage of the self-priming system. You prime (fill the pump and suction piping with water) only ONCE, at the initial installation. After that, the pump maintains suction automatically through the internal diffuser, even after long stops or loss of water column.
Yes — the PJm-100S is ideal for pressurizing buildings and condominiums up to 6 floors. With 40 mca maximum pressure, it ensures faucets, showers and toilets work with adequate force even on higher floors. For buildings taller than 6 floors, consult a professional for proper sizing.
