A 7.5hp vertical centrifugal pump arrived in the afternoon today. It took me about an hour to install, everything went as planned. The sealing is good, and there is no leakage problem. This pump runs so quiet that I couldn't hear it until I got right next to it.
Discounted price 5.5 kW 7.5 hp DC to AC solar pump inverter, MPPT 350~750V DC and 3 phase AC 240v/415v/480v input solar VFD for PV pump, automatically sleep when on high-water level and automatic restart when on low-water level.
Low cost 7.5 kW (10 hp) solar pump inverter / controller, input voltage from 450V DC to 750V DC drive three phase 220V AC, 380V AC, 480V AC water pump, grid and solar energy is switchable, adopting advanced MPPT technology, make full use of the efficiency of the solar cell array.
7.5 hp horizontal centrifugal pump has maximum flow 7.8m3/h (34.3 gpm), maximum head 72m (236ft) and same diameter of inlet and outlet 40mm(1-1/2 inch). 3 phase centrifugal pump also has optional input voltage AC 230V/240V/380V/440V to 480V and optional input frequency 50Hz/60Hz, can be used for garden sprinkler irrigation, HVAC & refrigeration water circulation, etc.
10 hp vertical centrifugal pump adopts single stage impeller, with maximum flow 65m3/h (286 gpm), maximum head 35m (115ft), same diameter of inlet and outlet 80mm (3 inch), optional input voltage 3 phase AC 230V/ 240V/ 380V/ 415V/ 460V/ 480V and optional input frequency 50Hz/60Hz. 10 hp centrifugal pump can be installed in the pipeline for pipeline pressurization, or operate in series or parallel connection for high flow/ high head water supply.
