Submersible Pump by Rehoboth Agencies

Our company has set benchmark in offering 60Hz Submersible Pump to the clients. 60Hz Submersible Pump is designed and made in compliance with quality standards under the supervision of professionals at vendor’s end. This product is known to deliver optimum performance to the clients. Furthermore, we are providing this at economical rates.

Features:

• Compact design
• High strength
• Low maintenance

Other information:

A WIDE PUMP RANGE:

• We offer submersible pumps with energy- efficient duty points ranging from 7 GPM to 1100 GPM. The pump range consists of many pump sizes and each pump size is available with an optional number of stages to match any duty point.

HIGH PUMP EFFICIENCY:

• Often pump efficiency is a neglected factor compared to the price variations and is without importance of pump and motor efficiencies

EXAMPLE:

• When pumping 125 m3/ h with a head of 200m for a period of 10 years $ 60,000 will be saved if pumps and motors having a 10% high efficiency are chosen and the price is $ 0.10 per kW.

APPLICATIONS:

• We offer a complete range of pumps and motors which as a standard are made completely of stainless steel AISI-304. This provides for good wear resistance and a reduced risk of corrosion when pumping ordinary cold water with a minor content of chloride.

Attributes:

LOW INSTALLATION COSTS:

• Stainless steel means low weight facilitating the handling of pumps and resulting in low equipment costs and reduced installation and service time. In addition pumps will be as new after service due to the high wear resistance of stainless steel

BEARINGS WITH SAND CHANNELS:

• All bearings are water- lubricated and have a square shape, enabling sand particles, if any, to leave the pump together with the pumped liquid.

INLET STRAINER:

• The inlet strainer prevents particles over a certain size from entering the pump.

NON-RETURN VALVE:

• All pumps are equipped with a reliable non-return valve in the valve casing preventing back flow in connection with pump stoppage.
• Furthermore, the short closing time of the non-return valve means that the risk of destructive water hammer is reduced to a minimum.
• The valve casing is designed for optimum hydraulic properties to minimize the pressure loss across the valve and, thus, contributes to the high efficiency of the pump.

PRIMING SCREW:

• All QF and QF 30 pumps are fitted with a priming screw. Consequently, dry running is prevented because the priming screw will make sure that pump bearing are always lubricated.
• Due to the semi-axial impellers of large QF pumps (except for QF 30) this priming is automatically provided.
• However, it applies to all pump types that if the water table is lowered to a level below the pump inlet neither pump nor motor will be protected against dry running.

STOP RING:

• The stop ring prevents damage to the pump during transport and in case of up-thrust in connection with start-up.
• The stop ring, which is designed as a thrust bearing limits axial movements of the pump shaft.

Example: QF 125:

• The stationary part of the stop ring (A) is secured in the top bowl (Upper intermediate chamber). The rotating part (B) is fitted above the collet [split cone(c)].
