6 -100

DP Vertical pump in superior grade AISI 316 (1.4401) 40 Bar. Round flanges DIN or ASME. Pump model indicates nominal flow in [m3/h].

Indicates number of impeller stages (100 = 10).

Description of the product

The vertical, single or multistage pump serie DPLHS is designed for pumping clean, watery liquids. Suction and discharge of the pump are in-line, making the pump easy to install. The hydraulic assembly is installed vertically and driven by an electric motor.

4

All hydraulic parts of the pump are made of stainless steel, making the pump light and extremely suitable for applications that demand high grade materials, such as drinking water applications.

The DPLHS is designed for high pressures (up to 40 Bar)

1.4

Operation

Pump type Viscosity liquid [cSt]

The liquid is sucked in through the pump inlet (A) on the supply side under minimum pressure. The pump increases the pressure. The liquid leaves the pump through the pump outlet (B) on the delivery side under increased pressure.

Higher temperatures are possible at lower pressure.

For specific limits consult your supplier.

Contact your supplier for more detailed advice.

For standard motors see the technical specifications.

When the pump is fitted with another motor brand, please consult the motor supplier.

Pumps that are intended for 50Hz operation, may not be connected to 60Hz.

Performance characteristics

2.1

Performance curve details

The preceding diagrams give a global overview of all the pump models mentioned in this documentation.

Detailed characteristics are given for each model showing the hydraulic efficiency, NPSHreq, and shaft power as well.

The performance of the pump depends on the number of stages. The number of stages are shown as a multiple of 10, as per example:

DPHS 6-100

10 stage impellers

The detailed performance curves are in accordance with ISO 9906:2012 (Grade 3B). Vibration limits at rated speed and rated flow are according to ISO 9905.

The motors used for the measurements are standard DP. When using another motor brand the performance data, like Q/H, efficiency and shaft power must be corrected accordingly.

The characteristics given are based on: • De-aerated water at a temperature of 20 °C • Density of 1 kg/dm3 • Kinematical viscosity of 1 mm2/s (1 cst) To prevent the pump from overheating, gathering gas, cavitation etc. a minimum flow has to be secured.

The minimum flow corresponds to a percentage of the optimum flow Qopt in relation to the temperature of the liquid pumped.

2.2 6

Minimum efficiency index

The minimum energy-efficiency level according to the ErP regulations for water pumps is specified by the minimum efficiency index MEI. A high MEI value indicates a high efficiency of the determined pump.From 1 January 2015 on the minimum efficiency index (MEI) for standardised water pumps is ≥ 0.4.

2.3

Performance with variable frequency drive

The minimum frequency of the DP motor should be limited to 25 Hz to ensure sufficient cooling. When the rotational speed exceeds the nominal speed of the motor, make sure that the power output of the motor is suitable to drive the corresponding pump model.

The performance of the pump differs from the fixed speed performance according to the recalculation scheme.

The standard DP-Pumps motors are specially designed to drive the pump. When a standard IEC or NEMA norm motor has to be installed (or a special motor to fulfill the applications requirement, like explosion proof, high efficiency) a special bearing housing must be installed to relieve the motor of the axial force created by the pump.

ATTENTION Only a motor with a standard key can be installed with a thrust bearing housing.

ATTENTION There is no need to change the motor stool of the pump. The bearing flange can be mounted on the standard motor stool of the pump.
