4” multi-impeller borehole pumps for clean water, designed for water boosting, gardening and irrigation, lifting water from
boreholes in residential building service, commercial building service and irrigation systems also for agriculture. The S4 pumps must be
installed in wells with a diameter of at least 4”, or in tanks or cisterns and it increases the pressure of water that can then be used for
example to water medium or large gardens or (in the case of models with a greater flow and head) in irrigation systems in agriculture.

CONSTRUCTION FEATURES OF THE PUMP
Technopolymer impellers housed with stainless steel adjustment rings. Pump liner, shaft, coupling with motor, integrated suction filter and cable guard
are in stainless steel. Suction and delivery supports in micro-cast AISI 304 stainless steel. Removable built-in non-return valve in technopolymer or with
stainless steel plate (depending on model, see the material table). Technopolymer impellers designed to ensure high levels of efficiency in accordance
with PEI Directive starting from 25 GPM. NSF61 certificate is pending approval.
CONSTRUCTION FEATURES OF THE MOTOR
Pump can be coupled with 4” motors : 4GG, 4TW and 4GX.
4GG motors line includes single phase and three phase motors from 0.5 HP to 10 HP. 4TW is a single phase, 2 wire line from 0.5 HP to 1.5 HP. They are
built based on resin canned stator technology. 4GG and 4GX single phase motors have to be installed with a control box, 4CBUS line sold separately, in
the three-phase version the protection must be guaranteed by the user.
4TW motors are operated without starting control box, based on 2 wire technology with internal capacitor and thermal protector.
All parts in contact with water of 4GG and 4TW made in SS304, 4GX in full SS316.
All motors come with CSA approval, NSF61 is pending in process.
Suitable for use with Variable Speed Drive ( 30-60 Hz ).
