Design Specifications

The Blake Hydram Ram Pump, at its optimum will pump 20% of the water that is available to it, to a maximum height of approximately 150 m. The product can operate 24/7 for many years. Operation requires a steady source of running water (drive water) at a minimum speed of 7 L/min for a minimum head of 1 m.

The performance of the Blake Hydram is determined by the supply head, delivery head and by the input flow. The table below specifies the output factor in L/day. For every L/min of water flowing into the Blake Hydram, the amount delivered will be this factor in lL/day. For example, for a fall of 6 m, a delivery head of 20 m and an input flow of 10 L/min, then the output flow will be 2820 L/day (282 x 10).
Blake Hydram is available in sizes No. 1- No.8. depending on the site requirements.

Product Schematics

Technical Support

Blake Hydram servicing can be performed by the individuals who installed the system. Troubleshooting procedures and additional support is provided by Allspeeds.

Lifecycle

The product does not specify a design life. According to Allspeeds, some customers have had non-stop service from their hydram pump since the 1920’s and 30’s.

Manufacturer Specified Performance Parameters

The manufacturer specifies the Blake Hydram, at optimal performance, will pump about 20% of the input water to a maximum height of approximately 150 m. Other performance targets include: no running costs, no fuel or electricity, no pollution, operates 24 hours a day all year.

Vetted Performance Status

Testing performed by the China Institute of Water Resources and Hydropower Research determined when the delivery head is lower than 50 m, the efficiency of the Blake Hydram ranges between 55% and 65%.

Safety

The use of heavy wall steel tube for the drive pipe is highly recommended. Upon completion of the installation the operator must ensure the pump is firmly bolted to its concrete base and the drive pipes have been laid out evenly.

Complementary Technical Systems

The Blake Hydram base, at a minimum a simple concrete slab <150 mm thick,  provides a surface on which the hydram may be bolted and which absorbs the pulsations during operation. An enclosure for the Blake Hydram is also ideal as it protects the unit and prevents pollution.
