Plated Steel Suction Strainers; 1" to 6" Sizes Standard and Trash Types

All of our Dry Pit/Bearing Frame pumps incorporate the screw centrifugal impeller, invented by Hidrostal. This hydraulic design offers considerable benefits over conventional centrifugal pumps, including:

• Solids handling
• Viscous pumping
• Delicate handling
• Low shear pumping
• High efficiency operation

The unique characteristics of the screw impeller give a combination of characteristics not found in any other type of pump, namely:

• Extremely steep and stable curve
• High efficiencies
• Non-overloading power curve
• Low NPSH
• Non-clog pumping

The term ""Non-Clog"" has almost become a punchline in the pumping industry. Traditional wastewater pumps are actually classified as ""Non-Clog"", but ask any operator or pump mechanic if their ""Non-Clog"" pumps clog! The Hidrostal design takes solids handling operation to the next level, where clogging & blockages are a thing of the past. The Hidrostal is not a traditional non-clog pump, but actually a hybrid that utilizes the best features of a positive displacement type screw pump - crossed with a single vane centrifugal pump. This combination provides an unmatched performance of effectiveness & efficiency.

The fact of the matter is that unscreened sewage or wastewater is evolving and most of the pump suppliers are not evolving with it, but Hidrostal is.

The Hidrostal is not your ""average pump"", it is a unique alternative that is positioned to handle today's challenging wastewater demands. The superior hydraulic design is backed by a company that is committed to improvement and technology and is not just ""doing it the we always do"". Hidrostal offers our Dry Pit/Bearing Frame pumps in multiple installation types with several power transmission options. Our configuration features the Hidrostal wet end hydraulics with a robust bearing frame design with oversized bearings.

Hidrostal compact pumps allow non-clog, trouble-free operation in demanding situations. They are used in slurry and wastewater applications, by emergency management/fire brigades, on construction sites and even in private households.

Compact Pumps - small, portable and ready to use whenever needed.

Hidrostal compact pumps are heavy duty field units which combine usability and robustness with the superior hydraulic and solids handling performance of the famous screw centrifugal impeller. This makes it the preferred pump for all types of municipal and industrial wastewater, slurry and mud applications, but also flood defense applications for portable/stationary installations.

Typical Applications:

• Industrial effluent
• Viscous sludge
• Return activated sludge
• Drainage
• Process waste
• Sump cleanup
• Construction sites
• Flood defense
• Emergency management / fire brigades

Product Advantages:

• Solids handling of 50 mm (2") in diameter
• Robust unit capable of handling liquids containing fibrous matter
• Steep curve giving pressure reserve when pumping thick materials
• Mobile with a weight of 32 kg (70 lbs) including 10 m (33 ft) cable
• High efficiency and compact construction
• Non-overloading power curve
• Double mechanical seal arrangement
• Ex-proof setups available

Immersible Pumps Operate Continuously in Air and Under Water

Hidrostal Immersible pumps successfully handle difficult municipal and industrial wastewater. Viscous liquids, fragile flocs, and even live fish without problem.

Hidrostal's dry well immersible pumps have independent closed loop cooling that enables the motor to run either in a wet or dry well. As these immersible units do not use pumped media to cool the motors there are no problems of overheating due to slime build up in the cooling channel. The pumps are particularly suited for dry pit applications where the combination of the screw centrifugal impeller and immersible motor are the state-of-the art technology. Leakage of the pumped product is eliminated by tandem seals running in an oil bath, avoiding a situation commonly experienced with soft-packed glands. Hidrostal immersible waste water/sewage pump stations have frequently been mistaken for clean water stations, due to the lack of odor and the cleanliness of the buildings. Immersible pumps are particularly suitable for installation where quiet running, clean surroundings, reliable and long trouble-free operation are required.

Advantages

Advantages of Dry-Well Installation:

• Quiet running
• Cool exterior
• No leakage of product
• Compact, simple installation
• No exposed rotating shafts or couplings
• Pump easily opened for inspection
• Vertical or Horizontal installation
• Clean odor-free waste water pump stations

Advantages of Wet Pit Installation

• Pumps can be installed in the same manner as submersible pumps
• Liquid level can be drawn down to pump casing without risk of overheating the motor
• Shallower sumps compared to conventional submersible pump installations

PREROSTAL®: Matched Flow and Clean Wet-Wells

A method of matching pump outflow to pump station inflow without the need for additional flow control or additional electrical equipment such as inverter drives. A highly effective sump cleaning system without the need for any additional mechanical or electrical items, such as grinders, bar screens or mixers.

Product Advantages:

• Matches station outflow to inflow using fixed-speed motors
• Automatically removes floating and settled solids
• Shallower pump stations [compared to submersibles with On-Off controls]
• Alternative to Archimedes screw pumps
• Reduced construction costs due to prefabricated basin design

The PREROSTAL® Pre-rotation system is a unique, economical, uncomplicated method of automatically adjusting pumping volume to varying inflow rates using a constant speed motor and pump. It combines the screw centrifugal impeller characteristics of a Hidrostal pump with a specially configured vortex inducing chamber around the suction pipe of the pump. The chamber utilizes gravity to impart a fluid spin in the same direction of rotation as the pump impeller, and this spin produces a flow reduction without the necessity of changing pump speed. This method of matching pump outflow to pump station inflow eliminates the need for any electrical equipment such as inverter drives.

In addition the PREROSTAL® system is a highly effective sump cleaning system which does not require any additional items or moving parts. It is the ideal solution for handling variable flow applications with large solids.

The PRESOSTAL® system is a proven and cost effective alternative to Archimedes screw pumps or other methods that require complex controls or additional electrical/mechanical devices.
