Principle of Operation
Centrifugal pumps are able to move fluid by rotating an impeller inside the casing using a motor. As the impeller rotates, fluid is drawn into the pump and hits the impeller eye. The impeller then accelerates the fluid, imparting kinetic energy. This forces the fluid to the tips of the impeller vanes. Upon reaching the edge of the impeller, fluid falls into the casing, which causes the fluid to decelerate and gain higher pressure (fluid velocity is converted to pressure). Fluid is then pushed out of the discharge nozzle and out into the pipes.

- Air Conditioning
- Refrigeration
- Fire Protection
- Drainage
- Irrigation

Regent's Self-Priming Trash & Sewage Pumps
Regent’s Series Self Priming Trash and Sewage Pumps are designed for economical, heavy-duty, 24/7 trouble-free operation. Solids handling is one of their most important advantages, as some self-priming pumps cannot efficiently handle debris and large-sized solids.
In fact, these Regent pumps can pass solids with sizes up to 75mm in diameter without clogging and damaging. They are suitable for many pumping applications from clean water to caustic fluids.
Features & Benefits
- Inspection hole for easier maintenance
- Adjustable or select correct wear plate to control impeller clearance
- Cleaning cover for easy and quick cleaning or removal of clogging
- Back Pull-Out feature for easy maintenance and servicing
- Oil Lubricated Bearings
- Rugged construction for long reliable operational life
Specs
- MAX FLOW: 75 m3/h
- MAX HEAD: 30 m
- MAX SOLID PASSAGE: 75 mm
Principle of Operation
Self-priming pumps have 2 stages of operation. In the priming stage of the self-priming principle, the impeller rotates to generate vacuum at the center. This draws air into the pump from the suction. Simultaneously, the pump creates a cylindrical ring of fluid on the inside of the casing. This causes a gas-tight seal to form. Meanwhile, air bubbles are trapped in the fluid inside the pump and are forced out through the discharge port. As soon as air is expelled, the liquid returns to the pump. As the fluid gradually rises and all the air is discharged, the normal fluid pumping using centrifugal working principle commences.
Regent's Split-Case Pumps
Regent’s Megaflow Series consist of horizontal split-case pumps with mega high flow rates. The casing is axially split, thus allowing quick and easy maintenance. The top half of the casing can be removed, allowing access to the rotating element without disturbing pipework or removing the electric motor. Additionally, the Megaflow pumps use a service-friendly shaft with quick and easy assembly-disassembly rotor components.
The design also eliminates the use of threads that may wear out over time, thus extending pump life.

- Seal options
- Accessories and spare parts
- Baseplate/mountingv
Specs
- Flow rates up to 1000m3/h
- Pressures up to 200m
Principle of Operation
Split case horizontal pumps are designed with casings that come apart. The design allows for the top part of the case to be removed without disturbing the driver or associated piping. This allows for quick and easy inspection and repair of the rotor as needed. Split case horizontal pumps are usually axially-split. That is, the flange where the case splits is in the plane as the pump axis. As for the operation, they follow the conventional centrifugal pump principle where fluid enters into the impeller eye and is cast out by centrifugal force along its circumference through the impeller’s vane tips. The action of the impeller increases the fluid’s velocity and pressure and directs it towards the pump outlet.
Regent's Vortex Pumps
Regent’s Vortex pump range includes the Vorbloc and Superflow Series. Most of these models are derived from the standard Dinflow range and include a recessed impeller which creates a vortex within the pump casing. Smaller models are also included in the range, mainly for marine use.
Vortex pumps can be supplied as bareshaft pumps, long-coupled, base-mounted units, close-coupled motor pumps, or long column sump pumps.
Features & Benefits
- High strength material combinations
- Stainless steel shafts – varying grades for specific liquids

Principle of Operation
Vortex pumps, which are also known as recessed impeller pumps, create circular churning motion around an axis. This motion creates suction to flow into the volute and out through the discharge. Vortex motion may or may not be created by pressure differences of a fluid-solid mixture. Since the rotor is positioned farther back it allows for solids and even gases to pass without direct contact with the rotor. To create an efficient flow with the suspended particles, it is essential to generate a sufficiently powerful vortex to induce suction of the solid particles. This requires a very powerful pumping action with high horsepower. Vortex formations are dependent on fluid properties like density and viscosity. The rotors are also recessed for solids clearance, although at some cost to the pump efficiency.
