Pedrollo PD submersible motors are of the oil filled rewindable type designed to give exceptional reliability and efficiency in all borehole pumping applications. They are constructed principally from stainless steel AISI 316 making them robust and long lasting in harsh operating conditions.
Pedrollo Submersible Pumps are designed for a range of water pumping applications, from domestic to industrial use. With their high-quality construction and reliable performance, Pedrollo Submersible Pumps offer a cost-effective and durable solution for water pumping needs.
Pumps are fitted with integral two-pole Pedrollo motors constructed principally from stainless steel. A built-in thermal overload for motor protection is provided so the pump can be connected directly to the mains power supply through a 10A fuse or MCB.
The Pedrollo 4SR1/12 is a submersible pump designed for domestic and industrial water supply, irrigation systems, and pressure-boosting applications. It has a power output of 0.37 kW (0.5 HP) and is suitable for use with clean water containing no abrasive particles.
This pump is part of the 4SR range of submersible pumps manufactured by Pedrollo. The range includes pumps with power outputs ranging from 0.37 kW to 7.5 kW (0.5 HP to 10 HP) and is designed for use in a variety of applications
MOTOR
Pumps are coupled to Pedrollo two pole sealed oil filled motor constructed principally from AISI 316 stainless steel. QEM Control box is available for single phase pumps which incorporates a fused rotary switch, run indicator light, DOL starter and capacitor which can be connected directly to the mains power supply. Three phase motors require a remote starter and if irregular electrical supply is prevalent an additional quick tripping voltage sensing relay is recommended.
-0%
All pumps are fitted with hermetically sealed re-windable liquid cooled induction motors designed for continuous duty provided the pump is fully submerged. They should be connected directly to mains supply through a 10A MCB or switch fuse.

MOTOR
Pumps are provided with built-in non-overloading induction motors designed for continuous operation. A thermal cut-out is provided in the motor windings to protect against pump overload and the pump can be connected directly to the mains power supply through a 10amps fuse or MCB.

A well designed solar PV support structure is of paramount importance to the long term durability of any solar installation. Structures should be strong and secure and for both ground and roof mount systems be able to endure the substantial forces of the panel weights and high wind speeds
