WHY IT WORKS

Built for the job

Tsurumi LB-1500 Submersible Contractor Pump

The heavy-duty 1.5kW pump for high-output, high-head site drainage.

The Tsurumi LB1500 is the most powerful model in the LB Series, built for the toughest, highest-volume dewatering jobs. With the strongest flow and head in the range and a robust 32.5kg build, it's the choice for demanding construction, utilities and flood-defence applications where a smaller pump simply won't keep up.

Performance you can rely on

Power: 1.5kW (230V single-phase)
Max flow: 420 L/min
Max head: 17.5m
Discharge outlet: 50mm fixed vertical discharge for maximum strength and performance
Free passage: 6mm solids

Built to last in dirty water

Like the rest of the LB Series, the LB1500 uses a semi-vortex chromium-iron impeller, double silicon-carbide mechanical seal and Tsurumi's oil-lifter system for seal lubrication in any position. Rubber and urethane components resist abrasion from sand, silt and suspended solids, while the top-discharge design keeps the motor cool during extended operation.

Manual only

The LB1500 is supplied as a manual pump (no automatic float/sensor version), giving the operator full control for heavy-duty continuous dewatering.

HOW-TO

How-to videos

What is the Difference between a Manual & Automatic Water Pump?

Manual Pump - A pump that does not have a float control or pressure switch to start and stop. It will require an operator to control it.

Automatic Pump - A pump that has a float control or pressure switch to start and stop without an operator.

A float switch is a level controller that has a buoyant, water-tight device that lies
on a liquid, actuating a micro-switch when the level rises or falls, turning a pump on or off.

Which Hose Should I use with my Water Pump?

Layflat hose is very affordable but can kink. Depending on your use, you may be better using a reinforced suction delivery hose for your needs.

Suction delivery hose is ideal for pumping up stairs or over obstacles.

Jonathan Martin explains the differences to help you choose which hose is best for your scenario.

Common questions

Can the Tsurumi LB1500 pump dirty water or sewage?

It pumps dirty site water and floodwater, not sewage. The LB1500 is built for rainwater, groundwater, standing water and dirty water carrying sand and silt, with solids up to 6mm and water temperatures of 0 to 35°C. It is not designed for sewage, toilet waste, water with stringy or fibrous solids, or flammable liquids, and it should not be left to bury itself in sand.

Is there an automatic version of the LB1500?

No, the LB1500 is manual only, so it runs until you switch it off and suits attended, heavy-duty dewatering. There is no float or sensor version. If you need automatic switching, the LB800 is available with a Pendant float or Sensor switch, with up to 310 litres per minute and 15 metres of head.

See: Tsurumi LB800 Contractor Pump – Manual & Automatic

How much water will the LB1500 pump through 50 metres of hose?

About 280 litres per minute through 50m of layflat hose at a 2m lift, as a guide. The same guide gives about 350 litres per minute through 25m, 260 through 100m and 220 through 200m, against a maximum of 420 litres per minute. Maximum head is 17.5 metres, so flow falls further as the lift increases and as bends and fittings add resistance.

What size generator do I need for the LB1500, and is it 110V?

Allow at least a 6 kVA generator. The LB1500 is 230V single-phase only, so there is no 110V version and no transformer option. Check the generator's voltage and frequency match the pump, as generators can be inaccurate and low voltage can trip the motor's thermal protection. For 110V site power, the LB800 and LB480 are offered in 110V as well as 230V.

See: Tsurumi LB800 Contractor Pump – Manual & Automatic

What hose and fittings should I order with the LB1500?

Order 50mm (2 inch) hose and a clamp to suit. The LB1500 has a 2 inch outlet in a fixed vertical position, unlike the LB480 and LB800, whose outlets can be turned horizontal. 50mm layflat suits most discharge runs; use 50mm suction and delivery hose where you need a rigid line that will not kink where it leaves the pump. The box lists the pump and cable only, so add a 2 inch hose tail to your order to connect the hose.
