Pump Saci Sigma 403 M

Saci Sigma horizontal pressure pump

Saci is a Spanish company with more than 40 years of history offering solutions for water treatment, prioritizing respect for the environment and optimizing energy consumption. 

They offer a wide range of products for domestic and industrial use and different solutions to suit different installations. 

The Sigma series stands out for being a horizontal multicellular centrifugal electric pump, ideal for forming small or medium flow pressure equipment, small sprinkler irrigation, among other applications.

The Sigma pump offers the following advantages:

• High hydraulic efficiency
• Minimal power consumption
• Extremely silent
• More hygienic 
• Single-phase and three-phase models available
• Flow rates: from 0.1 m³/h to 21 m³/h
• Heights from 8 m.c.a. to 90 m.c.a.

General characteristics

• High performance and silent operation
• For both domestic and industrial pressurization equipment.
• Self-priming up to 2 meters
• 11/4" suction and delivery threads
• Maximum water temperature at 35ºC
• Maximum ambient temperature at 45ºC

Constructive characteristics

• AISI 304 stainless steel turbines and pump body.
• Diffuser in technopolymer injected with glass fiber
• Suction and discharge body GG-20, internally and externally painted with anti-rust paint by cataphoresis.
• Shaft in stainless steel AISI 431
• Mechanical seal in graphite and AISI 304 ceramic

Motor characteristics

• Asynchronous motor
• Closed with external ventilation, suitable for continuous operation
• IP55 protection degree
• Class F insulation (heating "B")
• Suitable for operation through frequency inverters.

A Presscontrol can be incorporated to this surface water pump. It is a device whose function is to order the automatic start and stop of the pump when opening or closing any tap or valve of the installation. 

We have two types of Presscontrol to incorporate to the Sigma multicellular pump, the Sacipress or the Autopress, you can acquire them separately.

Technical data Sigma 400 pump

We have different models of the Saci Sigma 400 series: 2 HP in single-phase and three-phase current and 3 HP in three-phase current.

In order to choose the right pump, it is important to know the flow rate, which will be calculated according to the water supply points and the number of houses. And the other important parameter is the pressure.

From the result of these parameters and using the following table, the ideal model will be chosen according to the manometric head and the flow rate.
