HYDRO SOLO-E SERIES
|
A Hydro Solo-E system consists of a CR pump which is a non-self-priming, vertical multistage centrifugal pump. The pumps are availables with a Grundfos standard motor (CR pumps) or a frequency-controlled motor (CRE pumps). All pumps are equipped with a maintenance-free cartridge mechanical shaft seal.
A Hydro Solo-E system consists of a CR pump which is a non-self-priming, vertical multistage centrifugal pump. The pumps are availables with a Grundfos standard motor (CR pumps) or a frequency-controlled motor (CRE pumps). All pumps are equipped with a maintenance-free cartridge mechanical shaft seal.
On the discharge side of the pump is fitted a stainless steel discharge pipe, a check valve, an isolating valve and a pressure transducer
A pressure gauge is also present in the system to measure the discharge pressure
A frequency controlled motor (Grundfos MLE motor) drives the CR pump for 1 phase 230V (1/2-1 ½ Hp) and 3 phase 460V (2-10 Hp) versions of Hydro Solo-E booster sets
All other 3 phase versions of Hydro Solo-E booster sets come with a CR pump driven by an externally mounted Variable Frequency Drive (VFD)
Installation
A Hydro Solo-E booster set must be installed in a well ventilated room to ensure sufficient cooling for the pump. Hydro Solo-E is not suitable for outdoor installation
The booster set should be placed with sufficient clearance around it
3 phase versions must have a disconnect ON/OFF switch for the supply voltage, which is not provided as a standard item with the unit. The main components of the Hydro Solo-E include the pump, motor and the Variable Frequency Drive
Motor
Grundfos standard motors – With external VFD
3 x 208-230V, 3 x 460V (15-30Hp), 3 x 575V
CR, CRI and CRN in a Hydro Solo-E system pumps are fitted with a Grundfos specified motor. The motors are all heavy-duty 2-pole, NEMA C-frame
Frequency-controlled motors – MLE motors (integrated VFD)
1 x 230V and 3 x 460V (2-10Hp)
CRE and CRIE pumps in a Hydro Solo-E system are fitted with a totally enclosed, fan-cooled, 2-pole frequency-controlled motor
