The HD80T is perfectly suited to De-watering and flood control:

• The 500MM unit can move approx 80 Tons or 19,000 gallons of water in 1 hour at 300 rpm.
• Can dewater brackish water with elements and sludge in the water.
• The pump has impellers that can run for many hours without maintenance.
• Corrosion free due to the metals and plastics used in production.
• No priming is needed. Pump operator does not need to come in contact with waste polluted floods.
• Static pump can be auto controlled in flood events, or manually operated by a single user.
• Can be statically installed in case of flood emergency or can be deployed using a mini excavator hydraulic fitting and attachment bracket assembly.

Kirloskar Brothers Limited (KBL) recently launched its new SP coupled pump set with an integrated IE4 motor, designed for effluent treatment plants, sewage treatment plants and dewatering applications.

The pump set has an AC induction motor design which achieves high levels of efficiency and is most suited to working in field conditions. The high levels of efficiency are coupled with a higher specific discharge which results in 14% less energy consumption when pumping the same amount of fluid.

The pump set has high grade F-Class insulation with the temperature rise limited to B-Class and its robust design can withstand extreme power fluctuation, ensuring the reliability and safety of the equipment. The fan and fan cover design are constructed for optimum power consumption and quiet operation.

The high quality of its mechanical seal eliminates leakage, ensures lower friction loss and protects the shaft from wear and can handle liquids with temperatures up to 120° C. The non-clog impeller can handle suspended soft solids of up to 40 mm and is coated with Cathodic Electro Deposition (CED) for corrosion resistance.

Tsurumi has unveiled the highest-flow versions of its HS Series pumps with the new HS3.75SL (manual) and the HSZ3.75SL (automatic) submersible, trash pump models.

Designed to handle high volume drainage at low head, the new models pump roughly twice as much water as the high head model HS3.75S for dewatering applications.

The new pumps offer a maximum flow rate of 140 GPM and maximum total dynamic head of 40 ft, with a motor input of just 0.75 kW. Compact and lightweight, the pumps’ wear parts are built from highly durable materials. The shaft incorporates Tsurumi’s original agitator to prevent air lock and to stir slurry efficiently.

The difference between the two models is that the HSZ3.75SL contains a simple float switch-equipped automatic sensor to prevent dry-running operation and to reduce power consumption, which makes it appropriate for night-time operations and construction works in dense residential areas.

Glenn Wieczorek, managing director of Tsurumi America, said: “These trash pumps handle debris, sand and solids that come in flooding water with minimum wear and clogging.”

 

The Blackhawk Technology Company has launched its Apollo-AC HD Electric piston pump, a grid-powered AC electric pump that combines heavy-duty, low-flow endurance with linear-rod simplicity.

Designed for deep-well sites, the Apollo-AC HD pumps flowable products regardless of their chemical composition or viscosity to depths of 600 ft (183 m) or flows to 3.0 gpm (11.4 lpm), depending upon the model.  Applications include landfill leachate, gas-well dewatering, low-flow remediation, condensate, biofuel and pipeline drip-leg sump.

All pumps in the Apollo-AC series offer 24/7 grid power with lower amp draws than comparable electric models.  The Scotch-yoke linear-rod driver works with positive-displacement piston-rod micro technology to allow pumping to well or sump bottom and dry-running without harm, regardless of vacuum. 

Drive actuators and power are mounted above the well or sump for simple installation and cleaner, safer, less-frequent servicing.  The Apollo-AC HD series pumps to 200°F (93°C), or higher with special component, and can be customised to sit requirements.  Apollo drivers also are available for solar pumping. 

Tsurumi’s new HS3.75SL submersible pump for dewatering tasks has a small, energy efficient motor with an output of 750 w, which can move 580 l/min of water and has a maximum head of almost 11 m.

The new model is safe to run dry and the water does not travel through the pump casing, but via the spiral-shaped housing base with side outlet (80 mm).  It weighs less than 20 kg, is only 45 cm high and comes with a large handle and a 10 m long rubber power cable for 230 V. The modular design allows many parts to be replaced with standard tools.

Tsurumi’s double internal mechanical seal made of silicon carbide provides resistance. In addition, the motor shaft is protected from abrasive water flow by a special protective sleeve with sealing ring and several sealing lips. If thicker materials have to be pumped off, the agitator at the suction opening allows the medium to flow more easily, with an impeller made of polyurethane, offering high levels of durability. Tsurumi’s centrifugal-based oil distributor ensures that the pump shaft is reliably lubricated.

Grundfos has released a new pump module in its most recent update to the company’s WellConnect App, enabling water well contractors to complete daily water system management tasks from their phone, tablet or computer.

The company said that as well as adding a new pump module, it has improved the well visualiser graphics and functionality, and made it possible for users to enter pump data independently of well information. The new module allows users to record pump end and motor information, pump panel and control information, pump installation details, and record site troubleshooting and test information.

Since the Grundfos WellConnect app launched in February 2020, water well contractors have been using the app to manage geophysical logs, well and pump records, and share data with their teams.

Users who register for WellConnect receive a free trial subscription. Water well contractors already signed up for the Grundfos WaterPRO Programme, Basic Level will receive free access to WellConnect throughout 2020. Premium Level installers will receive free access throughout 2021.

The Grundfos WellConnect app is available on Apple iOS, Google Play and on the Grundfos website.

 

Blackhawk Technology’s Apollo piston pumps, designed for landfill leachate, gas-well dewatering, condensate pump and low-flow remediation pumping, are now available with either solar panel or AC electric power configurations.

Both pumps feature a low-draw 3/8 hp motor and a linear-rod Scottish yoke mechanism with a newly designed stuffing box and cartridge seals. The driver motor, power and connections are mounted above the wellhead, away from the liquid being pumped.

The Apollo solar piston pump operates in latitudes as far north as Toronto. Solar Model 101 can work at depths to 400 ft (122 m) at flows to 1.1 gpm (4.1 lpm) The Solar Model 102 offers flows to 2.6 gpm (9.8 lpm) at depths to 175 ft (51 m). These models are designed for closed or remote sites.

The Apollo-AC electric piston pump Model 101 operates to depths of 230 ft (70 m) at flows to 1.4 gpm (5.3 lpm). AC Model 102 offers flows to 3.5 gpm (13.25 lpm) at depths to 100 ft (30.5 m).

All pumps can be customised with eco-friendly construction materials.

The Thompson Pump and Manufacturing Company has expanded its series of rotary wellpoint pumps with the new 6 in version, the model 6RW-DIS-4LE2T-X, designed for wellpoint and sock dewatering applications.

With unassisted priming and automatic re-priming, the 6RW pump features high air handling and large water volume capabilities of up to 1,400 gpm with heads up to 80 ft. It has operating speeds up to 2,000 rpm and a low HP engine for better fuel efficiency – an EPA Final Tier 4 Isuzu engine (model 4LE2T) with diesel oxidation catalyst (DOC) after treatment.

The 6RW pump can be used in place of a comparable 6 in vacuum or piston pump, making it a cost-effective dewatering option. Chris Thompson, president of Thompson Pump and Manufacturing Company, said that this version was created, in part, due to the high demand to expand the rotary pump family’s dewatering capabilities.

There is also an 8RW and 12RW version of the pump and all are equipped with abrasion and corrosion resistant parts, polyurethane rotors and stainless steel wear plates that can handle intense industrial and plant applications.
