Product Overview


9-SSW pumps


SSW Small Power Solar Deep Well Pump
SSW series pump can be powered by DC and solar, that is pump input power.While our SZW series pump refer to pump output power. If you need power above 1000W, high-voltage solar pump is better( we can provide 3SZW,4SZW and 6SZW), which can both be powered by solar,DC and AC. For this high-voltage pump, we can use thinner cable that can reduce loss.
Main Features
1.Higher Efficiency :It is equipped with permanent magnet synchronous motor which has high speed and higher efficiency compared to asynchronous motor. 
2.Small Size and Light Weight:The volume and weight is only 1/5 of other pump in the same specification.
3.Intelligent Operation:It can control the operation by limiting the floating ball and other methods.It can switch on and switch off by setting a time. It can perform water-less protection under the well and can protect pump motor from overheating and over-current automatically.
4.The pump works both at 50HZ and 60HZ, and also the head and flow can remain unchanged under wide voltage. The output is constant when the voltage pulsation happens.
5.This pump should be worked with our exclusive controller, owns frequency control and constant velocity.
6.Energy saving and complete functions. It can be applied in industry, agriculture, petrochemical industry, medicinal industry and other kinds of water process.

Solar Water Pump



MARSROCK developed a new generation deep well pump, equipped with high speed and high efficiency DC brush-less motor as the source of power.
Compared with convention deep well pump, this product is characterized by high speed, high efficiency, small size, light weight and intelligent operation. It can control the operation featuring constant current and constant voltage by means of pressure and flow. It can control the operation by limiting the floating ball and other methods.It can switch on and switch off by setting a time. It can perform water-less protection under the well and can protect pump motor from overheating and over-current automatically.The pump can show the working status of voltage, current, water pressure, flow and speed of motor and can sent out a code indication once failure occurs.
Synchronous Motor


12-Synchronous motor.jpg


Rotor of our permanent magnet synchronous motor is made of rate earth magnet, driven by a diver which works when gap between rotor and winding differs. Pump speed is decided by its driver. Rotating magnetic field of motor and stator keep rotating synchronously.
It can work under constant power, speed, and torque with quick reflection and precise control. With constant speed, it can keep the head and flow unchanged in wide range of voltage.
Its efficiency is 15% to 20% higher than other single-phase asynchronous motor (include loss from motor and controller) and 7% to 10% higher than three-phase asynchronous motor. And if we equip three-phase asynchronous motor with frequency conversion controller, permanent magnet synchronous motor can be 10% to 13% higher than it.
It is equipped with a controller which adopts DC frequency inverter technology. This controller can protect the motor when it is over-heated, over current and over loaded.
Motor speed can be designed as required. When speed is high, motor size will be smaller and material cost will be lower.
Waterproof Controller

11-Pump controller


This pump should be worked with our exclusive controller, The new generation solar water pump adopts advanced DC controller, the controller for this pump uses the latest DC inverter technology, have all kinds of functions, such as: soft start, constant pressure for water supply, also have the function especially for fountain, such as: simulation control, bus-mastering. Since the advanced design, the cost is lower, and take less time to keep maintenance. Mars Rock has experienced engineers to provide the suitable plan and good service after sale.
This pump works both at 50HZ and 60HZ, and also can remain the head and flow unchanged under wide voltage, output constant when the voltage pulsation happens. As this pump used high efficiency motor ( the max efficiency for motor is about 92%), the PF up to 0.99, after deducted the comprehensive loss of controller, the final efficiency still higher than the well pump driven by single phase asynchronous motor.






This pump is mainly used for all kinds of water supply and drainage, fountain, solar system and all other field requires deep well pump, widely used in industry, agriculture, petrochemical industry, medicinal industry and all kinds of water process. This pump has obvious advantages especially for those request high pump head and big power. It’s a new generation electromechanical integration well pump, and it would be the future direction of deep well pump development.
Basic Pump System Connection Method





Controller & Solar Panle Connection Method


2 pieces 24V solar panel in series connection.
Note:This is only one group, if power is not enough, just connect one or several groups and voltage will keep the same. Solar voltage means working voltage of solar panels, we mention 24V solar panel, and its open circuit voltage is 30-36V(changed with temperature)

4.How about the warranty?
The SZW series water solar pump’s warranty is one year.
5.Why there are two packed in one shipment?
Normally, there will be two boxes for one order. Because the pump is packed in cuboid and controller is packed in cube. It’s difficult to pack them together as the volume will be large.
But to Brazil buyer, only one package/carton/box is allowed by Brazilian custom in one shipment. So we have to arrange two shipping in one order. Of course this way will add some air cost but buyer must bear it.
6.Is the price includes the tax fee?
No. Only product cost + shipping cost has been included. Other costs, such as: tariff, additional charge remote districts service by express company without included. Buyer must pay for them if there will be such charge.
7.Can I declare lower value than my payment for order to avoid tax ?
According to Aliexpress policy, declare lower value than real payment is not be allowed. Especially to buyer from Brazil, the payment approve must be submitted when parcel arrives brazil custom. So before paying for your order, please contact with MARS ROCK sales to get other ways to avoid high tax.

Every pump must be tested in pool one by one before packed in factory. When you open and will find some water in package, for it has been tested in water.
9.To the whole solar water pump system, what kits should be ready? May I buy all from MARS ROCK ?
Yes, MARS ROCK can supply the whole system to you. It should includes:
Solar pump+ pump controller
Solar panel
PV mounting bracket
Others optional : Switch controller box(DC air switch, anti-thunder etc.), Floater, extension pump cable, combiner box
11.In order to get my cargo t in a short time, what other working should I check to MARS ROCK when I pay for my order now?
Your tax number( to Brazil, Chile,Argentina,Romania)
Your Full name (to Russia)
